Abstract

In order to study the heat transfer characteristics between two rough surfaces of two contacting blocks with different bulk temperatures and sliding reciprocating motion, a two-dimensional heat transfer model was used to analyze the dimensionless average heat flux, considering thermal contact conductance. The results of a series simulations were presented, covering a wide range of operating parameters including dimensionless amplitude ${\tilde{S}}_{0}$ , dimensionless frequency $\tilde{ω}$ , and measurements of interface conductance $ξ$ . The results show that the dimensionless average heat flux increases with the increase of dimensionless frequency and amplitude, and the dimensionless average heat flux rises sharply in the low range of $ξ$ and approaches to a steady state approximation when $ξ > 71, 500$ and $S_{0} > 8$ .
