WebPolytropic efficiency is another concept of efficiency often used in compressor evaluation. It is often referred as small stage or infinitesimal stage efficiency. It is the true aerodynamic efficiency exclusive of the pressure-ratio effect. The efficiency is the same as if the fluid is incompressible and identical with the hydraulic efficiency: WebGenerally, the compressor efficiency decreases at half-load conditions because the leakage loss increases at low rotational speed and the over-compression loss increases …
