turbines

Turbines are the machines that transform rotational energy from a fluid that is picked up by a rotor system into usable work or energy. Turbine is a work producing turbomachinery. A prime mover that converts kinetic and pressure energy of a fluid into shaft power which is then converted into electrical energy by the help of rotating the generator with the generated shaft power.

 A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels.

Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for the invention of the steam turbine is given both to the British engineer Sir Charles Parsons (1854–1931), for the invention of the reaction turbine and to Swedish engineer Gustaf de Laval (1845–1913), for the invention of the impulse turbine.Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery.

There are many types of turbines. A turbine can be classified according to a direction of flowing fluid, head at the inlet of turbine etc. These are –
