The guiding idea for developing Tesla turbine is the fact that in order to attain the highest efficiency, the changes in the velocity and direction of movement of fluid should be as gradual as possible. Therefore, the propelling fluid of Tesla turbine moves in natural paths or stream lines of least resistance.
A Tesla turbine consists of a set of smooth disks, with nozzles applying a moving fluid to the edge of the disk. The fluid drags on the disk by means of viscosity and the adhesion of the surface layer of the fluid. As the fluid slows and adds energy to the disks, it spirals into the center exhaust. Since the rotor has no projections, it is very sturdy.
