Aim

To implement Tesla Turbine for small scale commercial purposes by improving

the design of previous Tesla Turbine

Objectives

Design a 500 Watt Tesla Turbine

Fabrication of Turbine

Testing of Turbine

Working Principle

Works on boundary layer effect

The motion of fluid on a discs creates friction

that tends to rotate the discs

Fluid enter radially at the outer boundary of the disc

And exits axially at the center of the disc

The discs coupled with shaft transmits the power to outside

Complete testing setup

• Pump was used for input

• Flow rate and pressure were measured

• Input Power = Flow rate x Pressure

• For output, pulley was used

• Torque and RPM were measured

• Output Power = Torque x Angular velocity
