What is a Reaction Turbine? How does Reaction Turbine work?

WebbThe degree of reaction is defined as the ratio of isentropic heat drop in the moving blades to isentropic heat drop in the entire stage of reaction turbine. A very widely used design has half degree of reaction or 50% reaction and this is known as Parson’s turbine. This consists of symmetrical rotor and stator blades. WebbA reaction turbine has fixed rotor blades and a rotating nozzle. Newton’s third law of motion (actions and reactions are equal but opposite in direction) describes the working of the reaction turbine (RT). It produces force due to the water movement over the fixed blades of the rotor. cyst moon of irisWebbThe Parsons' reaction turbine has only moving blades only fixed blades identical fixed and moving blades fixed and moving blades of different shape.
