Does anyone have any experience with using the tesla turbine as a compressor? I had an idea to develop a supercharger based on Tesla's priciple. Any input would be apreciated.
Thanks
Jim

I think if it was more efficient or cost effective than existing centrifugal compressors it would be in wide spread use by now. It looks to me like it would be limited as far as maximum pressure ratio capability and prone to surge problems (pressure at the outlet overcoming the air flow through the compressor and causing reversion to the inlet)It seems to me the efficiency of this pump depends alot on the viscosity of the fluid being pumped, which is not much in the case of air. I'm not familiar with the uses of the Tesla Turbine though, maybe you could elaborate?

Have you checked out this book:http://lindsaybks.com/bks5/tturb/index.html

It's got a lot of information on various design possibilities for them. I showed it to a mechanical engineer (who promptly kept the book) and he was fairly impressed with the information in it. One thing to remember is that Tesla turbines don't seem to be very fault tolerant designs, meaning if you don't make it exactly right, you won't get good results out of it.

Depends on your design. Many simple turbines, including the Tesla, turn at high speeds like 50,000 RPM. If this is the case you will need to build/buy a herringbone gear set to convert to a more useful speed. Such units are very difficult to build and pricey.
