Tesla Turbine Experiment

Vishwam Shah | Shyam Dhokai

Abstract: Nikola Tesla invented this bladeless turbine (patented 1913) originally, which uses boundary layer effect to run and not impingement of fluid upon the blades as in conventional. There are number of discs sequentially mounted on a shaft and the fluid is made to flow in a tangential direction with considerable pressure onto the discs with the help of an efficient nozzle, then follows a spiral path towards the centre and exits axially. The discs rotate due to the basic properties of the fluid viscosity and adhesion, as momentum is transferred via this forces and kinetic energy of fluid is converted into the rotational energy of the shaft. Many researchers have studied this concept and given various improvements with proofs basically into two ways one suggesting modifying the design of various components involved while others to change the parameters involved. Here a model is made of Tesla turbine and effort is made to understand on how to increase the efficiency by experimenting on a few parameters.
