Definitions
- a compressor is a machine which accelerates gas particles to, ultimately, increase the pressure of a compressible fluid, e.g., a gas, through the use of mechanical energy.
- Compressors are used in a number of different applications, including operating as an initial stage of a gas turbine engine.
- centrifugal compressors in which mechanical energy operates on gas input to the compressor by way of centrifugal acceleration, e.g., by rotating a centrifugal impeller (sometimes also called a "rotor") by which the compressible fluid is passing.
- centrifugal compressors can be said to be part of a class of machinery known as “turbo machines” or “turbo rotating machines”.
