PREDICTIONS OF HEAT TRANSFER IN COMPRESSOR CYLINDERS.

Summary

2 MODELS ARE USED TO INVESTIGATE THE INSTANTANEOUS HEAT TRANSFER BETWEEN THE CYLINDER WALLS AND GAS IN A RECIPROCATING COMPRESSOR. ONE MODEL USES MASS AND ENERGY BALANCES ; HEAT TRANSFER BETWEEN THE CYLINDER WALLS AND THE GAS IS CALCULATED WITH A WIDELY USED CORRELATION FOR THE HEAT TRANSFER COEFFICIENT. THE OTHER MODEL SOLVES THE UNSTEADY CONTINUITY, MOMENTUM, AND ENERGY EQUATIONS FOR THE GAS IN THE CYLINDER. RESULTS FROM THE FINITE-DIFFERENCE MODEL AGREE QUITE WELL WITH THE PUBLISHED RESULTS AND SIMILAR COMPUTATIONS. THE INSTANTANEOUS HEAT TRANSFER PREDICTED BY THE SIMPLE MODEL IS AN ORDER OF MAGNITUDE LESS THAN THAT PREDICTED BY THE FINITE-DIFFERENCE MODEL.
