instructables Tesla-Turbine |
I just did some reading about the Tesla turbine. I heard of it before but never looked into what made it different. Vary interesting and elegantly simple. Daox If your set on building a turbine you should definitely check it out. It has no vanes or blades, so the points I made earlier wouldn't have much affect.
The Tesla turbine (in case you don't already know) is only made up of smooth closely spaced discs. Basically the surface area of the discs and fluid friction is what drives the turbine as the high speed fluid flows through the discs to the center where it is exhasuted. Its hard to say what the actual eff of this turbine is, I heard it is only about 40% but Tesla claimed 95%. He tended to exaggerate a lot but it sound like he used a variable nozzle to achieve the high eff so maybe its possible.
This turbine will have to go on the list of things to build when I'm retired with a large workshop.
