Design and Experiment of Rotating Fluid Flow in a Tesla Disc Turbine

Turbine discs were designed and building a prototype to improve the efficiency of the working fluid in Tesla turbines. The fluid flow field within tesla disc turbine have been investigated experimentally. The turbine is a bladeless centripetal and tangential flow turbine. The turbine runs by the principle of momentum transfer by developing a boundary layer on the smooth surfaces of the disks. Circular nozzles were analyzed using air as the working fluid and flow taken to be incompressible, turbulent and non-reacting. Different inlet velocity ranging from 20.0 to 70.0 m/s has been investigated. In the range investigated the lower velocity did not influenced the performance. Paper will develop an adequate design of nozzles contribute to increase the overall yield of a Tesla turbine.
