Design, Fabrication and Analysis of Bladeless Turbine

A bladeless turbine is capable of using the exhaust gas energy adiabatically by converting most of its energy into shaft power. This bladeless turbine is widely known as Boundary-layer turbine or Cohesion-type turbine. The fundamental physics behind the working of the bladeless turbine is boundary layer effect; boundary layer is the layer of fluid in the immediate vicinity of a bounding surface where the effects of viscosity are significant. The heat energy that is being wasted as exhaust in a four-stroke engine can be utilized by using a bladeless turbine which is capable of converting a fast-moving fluid (exhaust gas) to shaft work. This shaft work can be used for various applications like to run an alternator or a compressor. The prototype model of bladeless Turbine has been designed and tested with different experiments were made under varying mass air flow rate of compressed air.
