Numerical analysis of unsteady behaviour of a screw compressor plant system

In order to analyse the performance of screw compressors operating under varying load conditions, an unsteady one dimensional model of the compressor process was modified to include all plant components, including tanks and connecting piping. This was based on the differential equations of conservation of mass and energy. The results derived from this model have been verified by experiment in order to obtain a reliable tool that can simulate a variety of scenarios which may occur in everyday compressor plant practice
