Contribution towards modelling of two-stage reciprocating compressors

Abstract The paper presents the results of simulation of a two-stage two-cylinder reciprocating compressor system with inter- and after-cooling. The equations representing the unsteady gas flow in the piping system, with inclusion of friction and heat transfer effects, were solved in the characteristic form by means of the modified Benson numerical mesh-method. The predicted results were compared with the experimental data showing good agreement.
