Turbine
1. Turbine is a machine for producing continuous power in which a wheel or rotor, typically fitted with vanes, is made to revolve by a fast-moving flow of water, steam, gas, air, or other fluid.
2. A turbine is a machine that transforms rotational energy from a fluid that is picked up by a rotor system into usable work or energy.
Turbines are generally used in electrical generation, engines, and propulsion systems. Turbines are machines (specifically turbomachines) because turbines transmit and modify energy. A simple turbine is composed of a series of blades – currently steel is one of the most common materials used – and allows the fluid to enter the turbine, pushing the blades. These blades spin while the fluid flows through, capturing some of the energy as rotational motion. Fluid flowing through a turbine loses kinetic energy and exits the turbine with less energy than it started with.
Turbines are used in many different areas, and each type of turbine has a slightly different construction to perform its job properly. Turbines are used in wind power, hydropower, in heat engines, and for propulsion. Turbines are extremely important because of the fact that nearly all electricity is produced by turning mechanical energy from a turbine into electrical energy via a generator.
