Turbines are used in gas turbine engines on land, sea and air. Turbochargers are used on piston engines. Gas turbines have very high power densities (i.e. the ratio of power to mass, or power to volume) because they run at very high speeds.

2025年2月10日 · turbine, any of various devices that convert the energy in a stream of fluid into mechanical energy. The conversion is generally accomplished by passing the fluid through a system of stationary passages or vanes that alternate with passages consisting of finlike blades attached to a rotor.

又称涡轮或涡轮机，透平是英文turbine的音译，源于拉丁文turbo一词，意为旋转物体。 透平的工作条件和所用工质不同，所以它的结构形式多种多样，但基本原理相似。 透平的最主要的部件是一个旋转件即转子，或称叶轮，它安装在透平轴上具有沿均匀排列的叶片，流体所具能量在流动中，经过喷管时转换成功能，流过叶轮时流体冲击叶轮，推动叶轮转动，从而驱动透平轴旋转，输出机械功。 透平机的 工质 可以是气体，如：蒸汽、燃气、空气、其他气体或混合气。 也可以是 …

2022年1月13日 · A windmill is the simplest kind of turbine: a machine designed to capture some of the energy from a moving fluid (a liquid or a gas) so it can be put to use. As the wind blows past a windmill's sails, they rotate, removing some of the wind's kinetic energy (energy of movement) and converting it into mechanical energy that turns heavy, rotating ...

A turbine is a machine that plays a key role in transforming fluid or air energy into usable work or electricity. With a rotor system at its core, a turbine harnesses the rotational energy generated by the fluid to produce a wide range of applications.

What is a Turbine? A turbine is a rotating machine that converts kinetic, potential, and thermal energy into mechanical energy. Three types of fluids are used in it: Steam; Gas; Water; The turbine primarily acts as a prime mover that helps rotate the rotor of …

2024年2月23日 · The oxford dictionary describes a turbine as “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.”

2024年8月31日 · Turbine Machine: The basic principle behind a turbine machine is the conversion of energy. In a steam turbine, this involves converting high-pressure, high-temperature steam into rotational energy through a series of blades or vanes. This rotational energy is then used to drive a generator, which produces electricity.

A turbine is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful mechanical and electrical energy. This means the work produced by a turbine can be used for generating electrical power when combined with a generator.

1 天前 · Turbine design and selection depend on water flow and the head at the site, ranging from low to high head. ... Following are the main applications when a machine suddenly rejects the load. When a large area like a 550 kV line trips or big power equipment fails, the large amount of load is disconnected as a result, and the huge dip in the system ...
