Further improvements have been made after plenty of r d from the last turbine.
Ceramic tesla turbine.
It is referred to as a bladeless turbine the tesla turbine is also known as the boundary layer turbine cohesion type turbine and prandtl layer turbine after ludwig prandtl because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional turbine.
Apologies for the camera work.
Build a 15 000 rpm tesla turbine using hard drive platters.
In the tesla turbine air steam oil or any other fluid is injected at the edge of a series of smooth parallel disks.
Once again this turbine eagerly is awaited.
A tesla turbine is a quite unique technology.
This test was done without preloading the bearings.
The tesla turbine efficiency has increase it now has ceramic bearings and it is now close loop which makes it ideal for organic rankine cycle systems.
The bearings were damaged as a.
The fluid spirals inwards and is exhausted th.
Here s a project that uses some of those dead hard drives you ve got lying around.
The us patent 1061206 was granted on the 6th may 1913 although historical documents suggest that that tesla first showed a 200 horsepower about 150kw 16 000.
