CAD Animation of Tesla CD Turbine

Here's an animation of our Tesla CD Turbine.

Created for Cornell's Mechanical Engineering air cart project:

What was the program you used to create this animation, please reply..

The gaps are only optimal at silly speeds in your deisgn, consider redesigning it with the optimal boundary layer in mind Pi(sqrt(kinematic viscosity of the fluid/ the angular velocity of the turbine))

[smoseson]

@fr0ber We designed the turbine to work at w = 9,000 rev/min (942 rad/s). Using your equation with kinematic viscosity, v = 15.68e-6 m^2/s I get:

pi*sqrt(v / w)

= pi*sqrt(15.68e-6 / 942)

= 0.405 mm

The washer spacers we used were 0.5 mm thickness.

good work

can anyone make a powerful Tesla turbine and moving a car with it ?

very nice animation!

@smoseson Oh ok Wow, I'm used to seeing effective RPM with the power linked ranging from 3000 to 6000.

But to be honest I thought the spacing compared to size was cooompletely different to that, just my failure at visualizing sizes I guess :)

Sorry but you dreaming, if you think a worm reduction drive has enough of a gear reduction - you need a planetary gearbox - these thinks can easily do 30 000 RPM

Look at the attached videos for the actual working turbine.
