In the modeling of heat transfer through cylinder wall of reciprocating gas compressor, thermal analysis software was developed to predict the transient heat transfer across the cylinder wall of a reciprocating gas compressor. The program was written in visual basics programming language. This software is used to analyze the temperature distribution profile across the compressor cylinder wall. The heat transfer was analysed for different cylinder wall thickness (that is variant 1 to variant 4) using Lump-Heat-Capacity Analysis approach. The developed model which is based on varying compressed gas temperature (Th) during compression has been validated using the reviewed model results as detailed in the work. In the reviewed model, constant compressed gas temperature was assumed, but in the developed model, varying compressed gas temperature (Th) was assumed. From the result, the curve for developed model (Rov) is closer to highest estimated compressed gas temperature (502K) than reviewed models (R01, R02, R03) curves at the same corresponding time. This indicates higher degree of accuracy for the developed model compared to reviewed models.
