Numerical heat transfer analysis considering thermal contact conductance between rough reciprocating sliding surfaces
Year: 2024
Type: article
Abstract: A finite element heat transfer model is constructed between two rough reciprocating sliding surfaces. Considering the effective thermal contact conductance, the heat transfer equations which consist of heat exchange due to temperature difference and frictional heat generation at the sliding interface are established. The influences of the reciprocating motion and the interface thermal contact conductance on the heat flow distribution coefficient and dimensionless surface contact temperature are solved by numerical simulations respectively. Furthermore, a prediction model is proposed based on the BP neural networks. This study provides a reference for the more accurate surface contact temperature calculation between rough reciprocating sliding interfaces.
