Abstract
Back in the 20th century, scientists proposed various methods for calculating the heat transfer coefficient, but, basically, they related to internal combustion engines. This paper presents an updated calculation of the heat transfer coefficient in relation to the compressor process occurring in the cylinder of a piston compressor with a linear drive. A comparison of various methods for calculating the heat transfer coefficient is carried out. The methodology proposed by the authors is implemented in the KOMDET-VKA-2021 package product.The obtained results revealed that,when calculating by other methods, the influence of the characteristic velocity in the process of gas suction into the reciprocating compressor cylinder is not taken into account. It should be noted that the closest result with respect to the KOMDET-VKA method was obtained according to the Eichelberg formula, but even in this variant, the characteristic velocity in the suction process is not taken into account. The results of the study show that taking into account the speed of gas movement in the cylinder leads to a more accurate determination of the heat transfer coefficient in the cylinder of a piston compressor with a linear drive, which further affects the determinatingother characteristics of the compressor.

Keywords: heat transfer, heat transfer coefficient, Woschni, Eichelberg, reciprocating compressor, numerical analysis.
