Summary

The discharge flow line has an important effect on the performance characteristics of a reciprocating compressor. At the beginning stage of a new compressor design, many prototypes should be prepared, and a long testing time is needed in order to decide on the optimum discharge system. In this study, CFD methodology is used to compare different design alternatives of discharge flow line. Appliance of CFD studies in new design projects aims to shorten test time and to reduce the number of prototypes. Differences in design of flow line include change in tube diameters and number of tubes. Mainly, six different alternative configurations are studied. The flow line between the cylinder head and discharge muffler is taken as CFD model geometry. Different mesh sizes are applied in order to verify mesh independency of analyses for all of the scenarios. Mass flow rate and pressure drop along the flow line are the parameters which are compared in order to decide optimum design alternative. Experimental studies are also conducted to verify CFD studies and to determine error rate. The resulting error rate is in an acceptable range so it can be deduced from this study that CFD is a useful tool to optimize such a discharge flow line.
