Abstract

The importance of developing thermal systems that effectively uses energy resources such as natural gas is apparent. Effective use is determined with both the first and second laws of thermodynamics. In this paper, an exergy analysis was presented based on the first and the second laws of thermodynamics to study in-cylinder properties of the air in a typical reciprocating compressor at each crank angle. A computer program has been developed to study the full operation cycle of an air compressor. The simulation used to calculate the pressure and temperature field existing in realistic compressor chambers for various engine speeds. The results show a good agreement with previous studies where applicable.
