The Tesla turbine is a bladeless centripetal flow turbine patented by Nikola Tesla in 1913.It was his 100th patent.Nozzles apply a moving fluid to the edges of a set of discs. The engine used smooth discs rotating in a chamber to generate rotational movement due to the exchange of momentum between the fluid and the discs.
The discs were arranged in an orientation similar to a stack of CD’s on a pole.The Tesla turbine uses the boundary-layer effect, instead of the method employed by more conventional turbines, wherein fluid turns the blades.Watch the video project from Integza:
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 through 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.
Tesla wrote: “This turbine is an efficient self-starting prime mover which may be operated as a steam or mixed fluid turbine at will, without changes in construction and is on this account very convenient.
