Centrifugal compressor
Thread Content
How is the compression ratio of a centrifugal compressor calculated? Thank you!
There is a set of professional software, and each company uses a slightly different version; in essence, it involves combining many impellers together to find the appropriate combination.
1. From an operational perspective, the pressure ratio is understood as the ratio of the absolute pressure at the outlet to that at the inlet. 2. From a mechanical design perspective, when selecting impeller parameters based on the pressure ratio, it is necessary to determine the pressure ratio for a given stage, that is, the pressure at the outlet of the stage divided by the pressure at its inlet
Compression ratio={Exit pressure (absolute pressure)+101.3Kpa}/{Inlet pressure (absolute pressure)+101.3Kpa}
