A method is described for simulating a single stage reciprocating compressor. A model is developed which allows for wave action in the intake and delivery systems, and drag and inertia of the valves. It is shown that homentropic theory may be used for the wave action, provided a correction is made for the entropy changes across the valve. The results are given of an experimental investigation in which the pressures in the intake and delivery systems, the cylinder pressures, the mass flow and the valve movement were compared with the predictions using the model. Good agreement was obtained over the wide range of test conditions.
