Performance improvement of a high pressure ratio ...

Centrifugal compressors with high pressure ratio have been widely used in small gas turbines, industrial compressors and turbochargers. High mechanical stress and high temperature of the impeller and large compression power required are the key factors that limit the pressure ratio achieved by centrifugal compressors.

Jan 07, 2020 Centrifugal compressors are much better for low pressure and high discharge operations because they work at a constant rate. The pressure ratio is also much lower at around one and four, while reciprocating compressors are around five and eight. A reciprocating compressure is far more flexible than centrifugal compressors and works better with ...
