Bladeless centripetal flow turbine
The Tesla turbine is a bladeless centripetal flow turbine patented by Nikola Tesla on October 21, 1913.[1] It was his 100th patent.[2]
Nozzles apply a moving fluid to the edges of a set of discs. The engine uses smooth discs rotating in a chamber to generate rotational movement due to the exchange of momentum between the fluid and the discs. The discs are arranged in an orientation similar to a stack of CDs on a pole.[3]
The Tesla turbine uses the boundary-layer effect, instead of the method employed by more conventional turbines, wherein a fluid acts on blades. The Tesla turbine is also referred to as the bladeless turbine, boundary-layer turbine, cohesion-type turbine, and Prandtl-layer turbine.
The latter is named for Ludwig Prandtl. Bioengineering researchers have additionally referred to the Tesla turbine as a multiple-disk centrifugal pump.[4][5]
One of Tesla’s intended implementations for this turbine was for the generation of geothermal power, which he described in his work Our Future Motive Power.[6]
In the pump, the radial or static pressure, due to centrifugal force, is added to the tangential or dynamic (pressure), thus increasing the effective head and assisting in the expulsion of the fluid. In the motor, on the contrary, the first named pressure, being opposed to that of the supply, reduces the effective head and the velocity of radial flow towards the center. Again, the propelled machine a great torque is always desirable, this calling for an increased number of disks and smaller distance of separation, while in the propelling machine, for numerous economic reasons, the rotary effort should be the smallest and the speed the greatest practicable.
In standard steam turbines, the steam has to press on the blades for the rotor to extract energy from the steam. In the bladed steam turbine, the blades must be carefully oriented in the optimal speed regime of the turbine’s work, to minimize the angle of attack to the blade surface area. In their words, in the optimal regime, the orientation of the blades is trying to minimize the angle (blade pitch) with which the steam is hitting their surface area, to create smooth steam flow, and to try to minimize turbulence. These eddies are created in reaction to the steam impacting (although the minimized angle in the optimal turbine speed) the surface of the blades. In this dynamic, eddies first cause a loss of the useful energy that can be extracted from the system, and second, as they are in opposite directions, they subtract from the energy of the incoming steam flow.[citation needed]
In the Tesla turbine, considering that there are no blades to be impacted, the mechanics of the reaction forces are different. The reaction force to the steam head pressure builds relatively quickly, as a steam pressure “belt” along the periphery of the turbine….
