Radial Flow Turbine Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14134

This experimental unit is designed to study the characteristic behavior of a reaction turbine using compressed air as the working medium. It demonstrates the fundamental principle of reaction or radial flow turbines: the conversion of pressure energy into kinetic energy within the rotor, resulting in the static pressure being higher in front of the rotor than behind it. The setup allows students to understand analogies to turbines powered by steam or water.

The apparatus is a closed, compressed air-operated system featuring a turbine rotor with four nozzle-shaped exits mounted in a transparent housing. The exiting air jet drives the rotor based on the reaction principle. Key parameters like torque, speed, pressure, and volumetric flow rate are measured and digitally displayed. A quick-action stop valve is included as a safety mechanism against over-speed.
