Experimental Investigation and Numerical Modelling of Dynamic Behaviour of Screw Compressor Plant

Abstract

An experimental and analytical study of screw compressor operation under unsteady conditions has been carried out. For this purpose a one dimensional model of the processes within a compressor was extended to include other plant components, including tanks and connecting piping. This was based on the differential equations of conservation of mass and energy. The results derived from the 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 operation. The analytical model was then further developed to demonstrate whole plant transient operation when a screw compressor is connected with storage tanks, control valves and heat exchangers in a complete system.
