Element Interactions and Dynamic Behaviour of Multistage Intercooled Reciprocating Compressors - an Analytical and Experimental Study

This paper describes a model which can simulate the dynamic behaviour 'Of a multi stage, intercooled reciprocating compressor. A mathematical model was derived for each element of such a system, accounting for entropy changes due to friction or uther irreversible processes. Numerical solution of the model was effected on a digital computer using discrete time steps and a quasi -steady approach. Results predicted using the model are compared with corresponding experimental results obtained from a simple two-stage intercooled air compressor.
