Methods of determination of polytrophic effectiveness factor of the centrifugal supercharger

Abstract

Mathematical models of determination of the polytrophic effectiveness factor (EF) of the centrifugal supercharger (CS) of natural gas were analyzed. On this basis four methods of calculation of polytrophic EF of CS were investigated. According to these four investigated methods there was carried out the practical calculation and comparison of changes of values of polytrophic efficiency of CS. The simplest method was allocated, that helps to determine the polytrophic EF of CS with entrance pressure of 0,5-2,3 MPa very quickly.
