Heat Transfer Analysis in the Cylinder of Reciprocating Compressor

Popis výsledku v původním jazyce

Heat transfer inside the cylinder of reciprocating compressor causes decrease of volumetric efficiency due to superheating of the working fluid. Understanding heat transfer phenomenon inside the cylinder is necessary to achieve higher efficiency. There are several empirical correlations available in the literature to date, which are employed in simulation tools due to their easy-to-use properties and they provide fast results with solid accuracy compared to more complex numerical models for heat transfer. Nevertheless, there is a problem with validation these empirical correlations. Solution of this problem could be found in CFD simulation tools. This paper presents the CFD analysis of heat transfer in order to compare heat fluxes calculated by numerical tools with those obtained by empirical correlations. Distribution of transferred heat among the main typical surfaces inside the cylinder is described in this paper. The analysis was done on simplified 3D geometry including the movement of valves and remeshing through the simulation to guarantee mesh quality. Based on the results of numerical analysis a proposal to increase the accuracy of heat transfer prediction is suggested.
