Do you know of any previous attempts to use a tesla turbine in a closed cycle (i.e., using two turbines, one as pump; hot on one join, cold on the other)?
@Fordi Unfortuantely no. I have seen no documentation to that. I have heard of the Turbines being used as pumps, but no commericial application of both a turbine and pump.
The reason I ask: I've been reading up on the use of supercritical CO2 as a working fluid in a closed externally heated Brayton cycle for high temperature gradient applications where steam turbines end up with a huge size requirement per watt.
It may be fun to try subbing in laminar adhesion turbines for the compression / power stages, rather than regular reaction turbines.
@Fordi I would recommend you examine the Magnox and UNGG nuclear power plants. They used CO2 as the coolant, and you might be able to find information on the CO2 properties used in those setups. If you want any help with the mathematics of your design, I would be happy to lend a hand.
@slanw probably, but you would have to put in a correct gear ratio to that the power of the turbine can be transferred into enough torque to move the car.
I have 1 doubt: You mention that the disk surfaces should be as smooth as possible. I was under the assumption that telsa turbine is a friction based pump and therefore the rougher the disk surfaces the more energy is transferred to the rotating disk. To what extent am I off with this assumption?
@mathayi2000 rough surfaces cause turbulence in a fluid flow. Turbulence causes an increase in entropy, thereby creating more energy losses in the system. With a smooth disc, most of the flow is laminar, and therefore less energy is lost to to irreversible changes in the system. Does this help? I can explain further if you wish...
@mathayi2000 Is not based on friction but in superficial forces of fluids, the same principle when you put water between 2 CDs and are hard to separate them.
@iggymydog D is the gap between the discs, and W is the angular velocity. If you want higher speeds, you need to decrease the disc gap (consistent with the fluids kinematic viscosity) in accordance with the equation:
W= n*(pi/D)^2, where n = kinematic viscosity of the fluid
So, if you were to somehow manufacture a tesla turbine whose disc space is continually adjustable, would you see more a more efficient output? I suppose you would therefore have to make the length of the chamber variable as well though?
@Curly7714 Instead, make a multiple stage Tesla Turbine, such as that found in a jet engine, by steadily decreasing the disc gap as one progresses through each stage...
Turbine: It seems counterintuitive that the fluid would want to move towards the center of the disk, but would prefer to fly outward from centrifugal force. Is the gap distance so small that fluids are attracted to both sides of gap more than centrifugal force, or is it just because the disks are built within bodies that prevent the fluid from flying off tangentially from the disk? Also, what about controlling the velocity of the disks by varying the incidence angle of the nozzel?
@008klm the reason that the most of the fluid would fly off the turbine is due to the formation of boundary layers over a surface from fluid mechanics. i suppose that you could control the angular velocity using the method u mentioned, but I think it would be simpler to vary the flow into the turbine.
Guys i have 2 questions. First - is it possible to construct such turbine in SolidWorks and to be calculated (simulated) successfully ? Secondly - you probably remember Mercedes SLR with it's turbine wheels. So - is it possible to use Tesla's turbine for that issue - to suck the air out of the clearance and to blow it outward ? The same like SLR's turbines ? Thank you!
At what scale do you think this breaks down? Could materials be engineered such that electrons would flow in a similar manner? Small currents produce increasingly larger magnetic field or something.
@heavym3tal It was probably a really silly comment. Your presentation was excellent and made me curious if there are materials in which the electrons flow with properties similar to the water or air in the tesla turbine. For example, if you replaced the empty space in the tesla turbine with graphene sheets connected by nano tubes and the flat disks with another material. Would the electrons flow in a similar manner as the water or air and create currents in the material of the disks?

What do we do with the result from the Boundry Layer equation? What does it represent physically? Also, what is the difference between the Relative Flow Vel (Va) and the Inlet Vel (U)?
@givemetoast The boundary layer (in the case of the Tesla Turbine) that you should be concerned with is the laminar boundary layer, which means that you would limit your Reynold's number to 2300 or less (beyond that, your boundary layer transitions to turbulence, decreasing the efficiency of the turbine). Setting this limit, a preliminary approximation would be incompressible flow over a flat plate. Do this in 1-D, then set other boundary conditions to the problem to do a 2-D approximation.
@givemetoast Since there have been no in-depth experimentation on such details, the general rule of thumb for designing the disc holes is: 1) as close to the center as possible, and 2) as many as possible. This of course will be limited by the material that you make the discs out of, which should be VERY smooth, if possible.
This is just what I was looking for! Thank you! Question tho. How do I optimize the efficiency of the airstream; that is, the shape and angle of the airflow entering the disk? Are there formulas for air shape (flat or round), thickness and angle?
@givemetoast you might want to look at some fluid mechanics books for information on that, but it depends on the fluid. You would want a very, VERY smooth pipe entering the inlet, but one that is not too long, as the boundary layer will transition to turbulent flow. I know that you are designing it, but I could be more help if you give me some information, or let me know the dimensions, and I will try and point you into the right areas.
You said that lightweight yet smooth discs would help increase performance of a tesla turbine. Would aluminum discs work or should you try something a little heavier bcuz I'm think that a prolonged use of the turbine would cause it give off lots of heat
@X02fighter If you use aluminum, you will have to limit the temperature of your working fluid about 100-200 deg below the melting point of Al, which is pretty low to begin with. If you could use a ceramic, you could increase your temperature up into the 1000-2000 deg regime. Don't forget that heat will diffuse through a solid from the hot end to the cold end.
@heavym3tal right that makes perfect sense but isn't ceramic fragile? I'm afraid that using ceramic discs might cause them to break or fracture if the revolutions per second get too high or if someone accidently drops it on the ground
@X02fighter dropping them yes, they will break/fracture. Unless your using non-industrial ceramic (dinner plates), they should hold up. I know tiles on the Space Shuttle were made from High Temperature ceramics, and I understand that they are experimenting with High Temp ceramics in jet turbines. The advantage of a Tesla Turbine lies in the fact that you can use low quality (non superheated) steam, while conventional turbines require high quality steam.
Don't worry about a clean T shirt laddie. You've just clarified the matter in simple terms for an old non-techie looking for answers. Priceless! Thank you!
@heavym3tal But may be i need to use something like BlowOff valve. Because the turbine will continue to spin. Something must stop the turbine. Or slow down. I`m just guesing not sure.
@xaviour39 Well technically it doesn't produce any energy. It extracts it from a working fluid. Now the amount of energy extracted depends on the efficiency of the engine in question. The highest experimental efficiency for a single stage Tesla Turbine has been about 35-40%. Theoretically, if you have laminar fluid flow over the surface, then you can achieve efficiencies in excess of 95%.
So you could use a Tesla Turbine paired with a Tesla Turbine/ or traditional turbine to power the former as a pump to increase the efficiency of said pump/turbine?
@dheiliger Not sure. Power plants are kinda complex systems to construct...but I'll be more than happy to help you design one with this type of turbine.
@heavym3tal - It would need to be designed using common material, and few special machined parts. If possible.
This could also be used as a hydraulic pump and , correct? Would one of these do that? With a few investors someone could manufacture these for several uses..
You said, that one guy claimed he could get 97% eff. Has any one really ever done that, and how did they over come the friction factor, to achieve it?
@dheiliger yes, this turbine can be used in reverse as a hydraulic pump. Tesla himself claimed greater than 90% efficiency, however, Dr. Warren Rice claimed that 97% efficiency could be attained with strictly laminar flow over the discs. His experiments yielded efficiencies between 30 and 40% i believe.
I am not sure what you are referring to when you mention friction factor though?
@heavym3tal Many modern turbines use both reaction and impulse principles. If the working fluid is compressible the reaction turbine is slightly more efficient at the cost of complexity. The famous Parsons ship turbine is a reaction type. The earliest Reaction turbine is the Aeolipile or Hero's engine, a very simple device.

@KenMacMillan | get a clue!!! the oil industry is the worlds richest industry!!!! OF COURSE FREE ENERGY MACHINES ARE NOT USED!!!!! the first fuel used for the first cars was ethanol - a type of alcohol, farmers used to make shitloads of it to sell as car fuel (lots of money) but then the rockerfellers gave a bunch of millions to a christian group against alcohol who then went and bribed the us government to enact ALCOHOL PROHIBITION!!!! this lasted long enough for the oil industry to take over..
@dljc1979 Even if you were right (& you're not), this isn't the same thing. This is simply a water turbine, something that he "evil" companies would want to use, not hide.
@KenMacMillan | you are so fucking clueless, THE OIL INDUSTRY IS THE RICHEST AND MOST POWERFUL INDUSTRY IN THE WORLD!!!!!!!!! WHY THE FUCK WOULD THEY SACRIFICE ALL THAT MONEY AND POWER TO GIVE PEOPLE CHEAP AND EASY ENERGY!!!!!!!!!!!!!!! ALL OF THIS STUFF WORKS AND THEY KEEP IT DOWN YOU STUPID SHIT!!!!!!!!!!!!! THE EVIDENCE OF HOW ALL THESE METHODS WORK IS ALL OVER THE FUCKING PLACE YOU THICK THICK BASTARD!!!!!!!!!!!! WAKE THE FUCK UP!!!!!!!!!!!!!! FUCKING GOD ALMIGHTY YOU THICK TWAT!!!!!!!!!!!!!
@dljc1979 Actually government is the richest & most powerful industry in the world. Oil companies would just use their money to produce something else people want to buy. Have you even bothered to look up the specs or the history of the tesla turbine? It was more efficient than the conventional turbine of its day because of the lack of aerodynamic theory needed for effective blade design & low quality materials. You can't even fix your caps lock.
Carnot's Theorem applies to a theoretical heat engine. The more appropriate thermal cycle might be closer to a rankine or brayton cycle, if you include your working fluid. Also, depending on the type of flow (Laminar, Transistion, or Turbulent) you have over the discs will change your efficiency.
I want to make a turbine in order to use it on a solar thermal project. Depending on efficiency (if it is around 30%) i hope it can give me around 1Hp mecanical power.
Which is more efficient : A Common turbine or a Tesla turbine?
@heavym3tal HEHEHE. First one to say that. Thought of the name from Teenage Mutant Hero Turtles - they love their Pizza's :) Anyway - great video, it got me thinking.
@FreePizza007 The word "Ninja"was censored for the word "Hero" because they thought "Ninja" would affect your mind. They are the Teenage Mutant Ninja Turtles. lol
Free energy technology exists!But the coverup is very strong,Go to LT-MAGNET-MOTORdotCOM and get the blueprints for a genuine magnet motor ,Let the revolution begin!
in other words it is nothing but that a water pump invested and works with air or water compresed, each disc multiplies the drag the water cause flowing through and cause a vortex in the cylinder increasing the power exponentially
I am very curious as to utilizing a tesla turbine design in supplement to a IC engine in a vehicle. Though to compete with current blade technology, it will have to manage at least 80% efficiency while spinning well over 100,000rpm.
The discs spin based on the the idea that at the boundary layer there is greater shear. How would this work if I were to pump a shear thinning fluid in (ie. Drilling Fluid)? Would the drilling fluid begin to thin due the the shear thinning effect and not spin the discs any more?
@TheIdrake Absolutely go for it. Start with the design that Nikola Tesla started with (holes near the center), then adjust disc spacing depending of the working fluid that you are working with.
@TheIdrake absolutely! i wanna try to make one, but actually im looking to make it as a pump... like heavymetal said, start with the original and go from there...If you can get your hands on matlab and maybe an engineering professor to help with the code if your not familiar or good with matlab you can design a nice machine. Matlab will let you simulate the turbine and change small parameters like disk diameter, thickness, spacing between them, hole size and you can find a good design!
Use large, rough sandblast shot, industrial stuff not beach sand a super fine sand blast shot would perhaps create too much of a seal - but maybe not it would have a smaller gap and more surface area - who knows we will have to give it a try - outer 2 disc surfaces need to be polished so the graphite seal only allows the the gas to escape via the internal sand blated surfaces
This will create a very small air gap. This simplifies manufacture there are no spacers, it also creates massive back pressure so the pressure diffential will be a lot higher than standard, also by sand blasting you increase the surface area a lot making it as difficult as possible for the gas to escape : )
So what I am proposing is a polished outer square, not rounded surface on the disks to make it as difficult as possible for the air to escape the internal high pressure high velocity generator, use a single high velocity impulse turnine nozzel in the center to propel the liquid ring super fast, then instead of spacers between the plates sand blast the sides of the plates and make them as rough as possible
Mr Tesla said you improve efficiency by making the gaps smaller and increasing the surface area - I have been a R&D machine designer for 22 years and in my wonderings I was taught that if you want to glue plastic pieces together you sand the surfaces to increase the surface area
Sorry I didnt finish my explanation I got the paintball gun to work it ran at 600 rounds per min and at 460 ft / sec how did I manage that well I designed a port to hold back the ball so it would create a pressure differential - so with low velocity high pressure gas I had an impulse propulsion system which is economical as high volume high pressure air/steam is expensive to generate.
@SvenOkonomi Nikola Tesla developed this turbine in the early 1900s, since it overcame a lot of the complexity of traditional bladed turbines. Personally, I think since more time and money has been spent studying bladed turbine design, those are the types that are most common. Tesla Turbines on the other hand have not been experimented and developed enough.
I am sorry but I dont agree with you at all on the smooth polished surfaces.
Here is why - pressure differential - I designed a paintball gun and in my ignorance I thought a 25 bar gas bottle would send them flying out, but I was wrong - the pressure was very high but the velocity was very low resulting in the paint ball rolling down the barrel and landing at my feet much to every ones amusement.
@maco10810 I'm not sure I can help you with your paintball gun design, but if you have a specific question on the aerodynamics of the tesla turbine discs that is unanswered here, reading about the boundary layer in a fluid dynamics book would be more helpful than myself probably.
OK so now what I am trying to do is this - and please correct me if I am wrong as I am going to build a car that uses steam to run this engine I dont want to build the engine twice as I cant afford any mistakes so in my opinion what I want to see in this engine is the following
Hi I am not as well educated as what you are, so this is not a contest, I have some theories which I would appreciate some opinions on.
In a high performance internal combustion engine you only polish the exhaust port pipes the inlet pipes are left rough to help mix the fuel with the air mixture.
@maco10810 Its not so much to help fuel mix with the air, but more so to reduce heat. Polished surfaces retain much more heat, and we want our exhausts ports to hold as much heat in as possible in order to increase velocity. Rougher inlet ports promote cooling of the intake charge as there is more surface area to flow over. Turbulent airflow is never good, thats why intake ports are still smooth just not polished.
In direct IC mode, Tesla intended his turbine as a pulsed combustion device. The wider disc spacing he used allowed more internal volume and to some extent the Ranque effect came into play with a noticeable increase in fuel efficiency. Have a look at his "valvular conduit", which contained combustion yet automatically allowed air and fuel flow once the previous fuel charge had been sufficiently consumed for vacuum to draw a fresh charge into the combustion chamber..
@complexjel2002 If you increase the efficiency of the device that converts heat into mechanical or electrical energy, then obviously you can reduce emissions for electrical generation.
@Kenzofeis If I get the chance to do more research with the tesla turbine, I would like to change the shape of the disc edges to airfoils, or maybe a parabolic shape. However, I do not know the outcome. If you get the chance please inform me of any progress :)
How scalable is the turbine I imagine you would want to keep the disks as thin as possible resulting in a limit on how large it is practical to make a disk. Also the larger the disk the more likely turbulent flow is to develop.
The answer to your question seems like an optimization problem, which would be interesting to find out. Also, the fluid properties of compressible flows (like gases) would require different disc gaps than that of incompressible flows (like liquids). I hope to eventually do some experimentation with the tesla turbine in the future and find out.
from where exactly is the air pulled axially when the discs are turned mechanically? im curious how the pressures between the axial draw of air and the tangential thrust compare without and with a housing (eg. a turbocharger). im also wondering if something of this nature could utilize a freefloating magnetic bearing.
The air is pulled when the turbine is used as a compressor. The direction is along a spiral path that starts at the edge of the disc and ends at the holes in the center. I believe that a freefloating magnetic bearing could help with the turbine.
so, upon being turned mechanically (by hand instead of by airflow along the discs edges), the air is pulled from the edges of the discs and ejected out the holes lined parallel to the axle? does the exiting flow come out both ends of the disc "stack"?
I am not sure which way the air exits the disc stack...however I believe that it depends on the rotational direction of the discs. Either way, yes, the air is ejected axially through the holes.
It swirls in finer and finer resolution as it moves towards the inside exhaust vents. Like the swirl in a whirlpool or toilet. Tesla said it was one of his most valuable inventions. Very cool turbines that can adjust torque with rotor weight. Solar boiling steam is free to boot,
ahh- without the container, the air would be able to apply force. the air creates an opportunity to create pressure against the sides of the container. Im not sure- Im not a physics major. , but it seems without the container to hold the air, that the air would just diffuse readily in the open atmposphere, and the turbine wouldn't work right.
in short,doesn't the boundary layer effect depend on pressure, not on the driving medium?
Its like saying that you could use another fluid to do the same thing. a fluid that doesnt mix readily with another fluid also being forced through the container- where one fluid representing the air, could pass through the turbine without turning it if it was at low enough pressures, but the other fluid representing air creating higher pressures against the surfaces and container would make it spin.
or what about a vaccuum? running it in a vaccuum/ low atmospheric conditions...you could use some other gas other than air, something super light, and still get the thing to spin...
but looking back at your post- i can see you were just referring to the direction of the flow... it has nothing to do with my longwinded replies! good presentation.
hey good video .. finally something with a bit of meat on the bone .. my thesis advisor is doing some geothermal power cycle research and if i remember correctly he's using a tesla turbine in one of his experiments ..
Got my Tesla Turbine Go Kart to work (sort of) Placed the video of it up on YouTube about a week ago. The thing was to weak to move me around, but it would slowly move by itself.
My Leaf Blower Powered Go Kart worked a little better.
About one 1/10 of an inch. The might be too close and it causing an air flow restriction. I'm going to address that on my next turbine, along with a diffrent housing shape.
I've just finished my TT go kart built of scrap lumber using seven inch dia. wheels. The six inch dia,. twenty disk, tesla turbine and it's electric leaf blower air source is connected to the left rear wheel using a fifteen to one friction drive. So far it's doesn't move an inch. (Not enough torque from the turbine)
I think if I try a diffrent housing, and larger drive ratio, it might be able to transport a forty lb. kid up and down the drive way. As my neighbor said "It's needs more work".
Pues estava pensando si la turbina tesla se podria ,de algun modo,ensamblar a un motor puntp cero para impulsarlo sin aire , agua o vapor . Y que tan combeniente serà almacenar la electricidad en baterias en lugar de ser tan libre. Muchas gracias por atender mis dudas, adio y exito en sus proyectos
On the other hand, Tesla detractors often use low output from air powered Tesla experiments to "prove" claims of inefficiency. Typical experiment: a 2.5 hp air compressor exhausts its capacity trying to produce 0.25 hp shaft output at the turbine.
But 2.5 Hp is a mfr. "peak" rating based on motor wattage. There are motor, compressor, and piping inefficiencies. In fact, delivered air to the engine is represents about 0.5 hp.
Most experimenters size their design too large for available air.
I built and tested a Tesla turbine 7 years ago from aluminum castings. I'm a fan, but concerned by the efficiency claims for made here and elsewhere.
My belief is that most Tesla supporters compare the heat content of fuels vs shaft output for IC engines. But they then use the steam heat content vs shaft output for turbine calcs.
The heat content of the fuel required to generate steam vs turbine shaft output should be used for efficiency claims.
A lot of Tesla Turbines that I see on youtube have disk spacing that is way too large for the fluid they are using (typically) air. If they use fractions of a millimeter for their spacing, the efficiency should increase.
Could this be applied to a skate?

I know that you are designing it, but I could be more help if you give me some information, or let me know the dimensions, and I will try and point you into the right areas.

You said that lightweight yet smooth discs would help increase performance of a tesla turbine. Would aluminum discs work or should you try something a little heavier bcuz I'm think that a prolonged use of the turbine would cause it give off lots of heat
X02fighter 9 months ago
@X02fighter If you use aluminum, you will have to limit the temperature of your working fluid about 100-200 deg below the melting point of Al, which is pretty low to begin with. If you could use a ceramic, you could increase your temperature up into the 1000-2000 deg regime. Don't forget that heat will diffuse through a solid from the hot end to the cold end.
heavym3tal 9 months ago
@heavym3tal right that makes perfect sense but isn't ceramic fragile? I'm afraid that using ceramic discs might cause them to break or fracture if the revolutions per second get too high or if someone accidently drops it on the ground
X02fighter 9 months ago
@X02fighter dropping them yes, they will break/fracture. Unless your using non-industrial ceramic (dinner plates), they should hold up. I know tiles on the Space Shuttle were made from High Temperature ceramics, and I understand that they are experimenting with High Temp ceramics in jet turbines. The advantage of a Tesla Turbine lies in the fact that you can use low quality (non superheated) steam, while conventional turbines require high quality steam.

using air to produce energy :o
xaviour39 10 months ago
@xaviour39 Well technically it doesn't produce any energy. It extracts it from a working fluid. Now the amount of energy extracted depends on the efficiency of the engine in question. The highest experimental efficiency for a single stage Tesla Turbine has been about 35-40%. Theoretically, if you have laminar fluid flow over the surface, then you can achieve efficiencies in excess of 95%.

@dheiliger yes, this turbine can be used in reverse as a hydraulic pump. Tesla himself claimed greater than 90% efficiency, however, Dr. Warren Rice claimed that 97% efficiency could be attained with strictly laminar flow over the discs. His experiments yielded efficiencies between 30 and 40% i believe.

Carnot's Theorem applies to a theoretical heat engine. The more appropriate thermal cycle might be closer to a rankine or brayton cycle, if you include your working fluid. Also, depending on the type of flow (Laminar, Transistion, or Turbulent) you have over the discs will change your efficiency.

Use large, rough sandblast shot, industrial stuff not beach sand a super fine sand blast shot would perhaps create too much of a seal - but maybe not it would have a smaller gap and more surface area - who knows we will have to give it a try - outer 2 disc surfaces need to be polished so the graphite seal only allows the the gas to escape via the internal sand blated surfaces
maco10810 1 year ago
This will create a very small air gap. This simplifies manufacture there are no spacers, it also creates massive back pressure so the pressure diffential will be a lot higher than standard, also by sand blasting you increase the surface area a lot making it as difficult as possible for the gas to escape : )
maco10810 1 year ago
So what I am proposing is a polished outer square, not rounded surface on the disks to make it as difficult as possible for the air to escape the internal high pressure high velocity generator, use a single high velocity impulse turnine nozzel in the center to propel the liquid ring super fast, then instead of spacers between the plates sand blast the sides of the plates and make them as rough as possible
maco10810 1 year ago
Mr Tesla said you improve efficiency by making the gaps smaller and increasing the surface area - I have been a R&D machine designer for 22 years and in my wonderings I was taught that if you want to glue plastic pieces together you sand the surfaces to increase the surface area
maco10810 1 year ago
Sorry I didnt finish my explanation I got the paintball gun to work it ran at 600 rounds per min and at 460 ft / sec how did I manage that well I designed a port to hold back the ball so it would create a pressure differential - so with low velocity high pressure gas I had an impulse propulsion system which is economical as high volume high pressure air/steam is expensive to generate.

@SvenOkonomi Nikola Tesla developed this turbine in the early 1900s, since it overcame a lot of the complexity of traditional bladed turbines.

Tesla Turbines on the other hand have not been experimented and developed enough.
heavym3tal 1 year ago 3
I am sorry but I dont agree with you at all on the smooth polished surfaces.
Here is why - pressure differential - I designed a paintball gun and in my ignorance I thought a 25 bar gas bottle would send them flying out, but I was wrong - the pressure was very high but the velocity was very low resulting in the paint ball rolling down the barrel and landing at my feet much to every ones amusement.
maco10810 1 year ago
@maco10810 I'm not sure I can help you with your paintball gun design, but if you have a specific question on the aerodynamics of the tesla turbine discs that is unanswered here, reading about the boundary layer in a fluid dynamics book would be more helpful than myself probably.

maco10810 1 year ago
Hi I am not as well educated as what you are, so this is not a contest, I have some theories which I would appreciate some opinions on.
In a high performance internal combustion engine you only polish the exhaust port pipes the inlet pipes are left rough to help mix the fuel with the air mixture.
maco10810 1 year ago
@maco10810 Its not so much to help fuel mix with the air, but more so to reduce heat. Polished surfaces retain much more heat, and we want our exhausts ports to hold as much heat in as possible in order to increase velocity. Rougher inlet ports promote cooling of the intake charge as there is more surface area to flow over. Turbulent airflow is never good, thats why intake ports are still smooth just not polished.

In direct IC mode, Tesla intended his turbine as a pulsed combustion device. The wider disc spacing he used allowed more internal volume and to some extent the Ranque effect came into play with a noticeable increase in fuel efficiency. Have a look at his "valvular conduit", which contained combustion yet automatically allowed air and fuel flow once the previous fuel charge had been sufficiently consumed for vacuum to draw a fresh charge into the combustion chamber..

How scalable is the turbine I imagine you would want to keep the disks as thin as possible resulting in a limit on how large it is practical to make a disk. Also the larger the disk the more likely turbulent flow is to develop.
davidatheist 2 years ago
The answer to your question seems like an optimization problem, which would be interesting to find out. Also, the fluid properties of compressible flows (like gases) would require different disc gaps than that of incompressible flows (like liquids). I hope to eventually do some experimentation with the tesla turbine in the future and find out.

from where exactly is the air pulled axially when the discs are turned mechanically? im curious how the pressures between the axial draw of air and the tangential thrust compare without and with a housing (eg. a turbocharger). im also wondering if something of this nature could utilize a freefloating magnetic bearing.
tfrostholm 2 years ago
The air is pulled when the turbine is used as a compressor. The direction is along a spiral path that starts at the edge of the disc and ends at the holes in the center. I believe that a freefloating magnetic bearing could help with the turbine.
heavym3tal 2 years ago
so, upon being turned mechanically (by hand instead of by airflow along the discs edges), the air is pulled from the edges of the discs and ejected out the holes lined parallel to the axle? does the exiting flow come out both ends of the disc "stack"?
tfrostholm 2 years ago
I am not sure which way the air exits the disc stack...however I believe that it depends on the rotational direction of the discs. Either way, yes, the air is ejected axially through the holes.

ahh- without the container, the air would be able to apply force. the air creates an opportunity to create pressure against the sides of the container. Im not sure- Im not a physics major. , but it seems without the container to hold the air, that the air would just diffuse readily in the open atmposphere, and the turbine wouldn't work right.
in short,doesn't the boundary layer effect depend on pressure, not on the driving medium?

Its like saying that you could use another fluid to do the same thing. a fluid that doesnt mix readily with another fluid also being forced through the container- where one fluid representing the air, could pass through the turbine without turning it if it was at low enough pressures, but the other fluid representing air creating higher pressures against the surfaces and container would make it spin.

On the other hand, Tesla detractors often use low output from air powered Tesla experiments to "prove" claims of inefficiency. Typical experiment: a 2.5 hp air compressor exhausts its capacity trying to produce 0.25 hp shaft output at the turbine.
But 2.5 Hp is a mfr. "peak" rating based on motor wattage. There are motor, compressor, and piping inefficiencies. In fact, delivered air to the engine is represents about 0.5 hp.
Most experimenters size their design too large for available air.
teslstirlputt 2 years ago
I built and tested a Tesla turbine 7 years ago from aluminum castings. I'm a fan, but concerned by the efficiency claims for made here and elsewhere.
My belief is that most Tesla supporters compare the heat content of fuels vs shaft output for IC engines. But they then use the steam heat content vs shaft output for turbine calcs.
The heat content of the fuel required to generate steam vs turbine shaft output should be used for efficiency claims.
We're comparing apples to oranges otherwise.

A lot of Tesla Turbines that I see on youtube have disk spacing that is way too large for the fluid they are using (typically) air. If they use fractions of a millimeter for their spacing, the efficiency should increase.
