Very good video thanks for posting this in such detail. Have you ever build a tube or worked out the internals? I have been experimenting with home made Vortex Tubes for some time- if you have any advice I'd appreciate it!
dis year gonna be my final year as student... so, i'm decided to make vortex tube as my final year project... i need to combined it with guide vane... my research is to decide which guide vane angle gonna give the optimum temperature ( the coolest )... so, anyone plzzz help me....
@imAGItating It's going to be darn noisy and big...
You need a compressor, giving 4 bar/55(ish) psi of compressed air, and and your air exhaust will be at about 50°C/120°F, not to mention the roar of 60-70% of the air compressed air coming out of the top!
You will be better off using a Pelletier cooling element in terms of size, weight and cooling efficiency.
Finally, if doing any heavy active cooling on a chip, beware of condensation on the mainboard... Bad things can happen!
Very professional set up! Any advice to someone building a hilsch cooling tube in their garage as an experiment? I built one awhile ago with PVC pipe and my air compressor. It worked but I'm interested on what I might do to improve it. Here is a link to what I built ottobelden.blogspot.com/2009/09/diy-homemade-ranque-hilsch-vortex.html
I've read a recent paper that vortex tubes can also operate by vacuum. If you are still in experiment mode do you mind following the same experimental process placing a vacuum on the outlets and leaaving the inlet open?
if a heat exchanger were attached to the cold side and used to cool the input, the input would get colder hence the output would get colder, which would start the cycle over again, like Carl Von Linde's apparatus. Do you think it would also get cold enough to liquify air?
My favorite description for the inner workings of a vortex tube is the "Original Secondary Circulation Model". Its a simple way of understanding the system in familiar terms (refrigeration/heat cycles). When vortex tubes are staged higher temperature separations can be achieved, but this would not come without a high energy cost. This is my Vortex tube grimoire.

Its an extremely thorough dissection of the device.
I haven't personally done it but it works well with all gases and it can even be used to create LNG. Whats really interesting is that it DOES work on incompressible fluids like water however, the effect isn't dramatic at all. But the fact that it works on water supports the Kinetic energy separation theory that states that part of the thermal separation is achieve by mechanically separate higher energy molecules from the lower energy molecules.
Perhaps I'm retarded, but wouldn't it be possible to use such an apparatus to generate h2/o2 from water vapor if it were constructed on some sort of molecular scale? Just a thought
Yeah these can be used to separate molecules or element with different weights, they are also used to separate isotopes but those are much higher tech. But since water vapor is still molecular h20 putting water vapor in would most likely produce steam and ice. If you split the water with electrolysis the mixed gas could be separated, but at that point its probably easier to collect both gasses in separate containers to begin with.
It is a separation of energy states. A high energy particle in the low energy section will collide lots. When it collides it transfers its energy a bit like a newtons cradle. The energy moves as a wave from one particle to another. When it reaches the high velocity outside and bumps in the right direction all the other particle are and moving at similar speeds and direction. The collisions are less energetic so it tends not to drift as much and so stay in that zone.
The Max COP We found was .2926 at a cold mass fraction of 0.6 The RSS of our math model gave about a 5% accuracy with a 95% probability used on our prediction intervals. They are very inefficient, Using a Carnot description the max COP would be 3.48.
The input pressure for this run was about 55 psi so 3.8 bar at 8 CFM--6 CFM on the hot side and about 2 on the cold. This is a commercially available tube its an AirTX model 20008. When the hot and cold flow rates were just right we were running at 0C and 100c.

nice.and very impressive.
have you tried making one by your self.
iam planning to build one for my homemade cnc milling,can you help me in making a vortex tube.

Have you tried any other gases e.g helium ? and does this effect work with liquids or vapors

Very nice setup whitube , In theory the COP of the vortex tube is around 0.2 what did you manage to get it at?

4bar and +18°C inlet, -21 °C on cold side, +46°C on hot. is this a commercial tube?
