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 S~0, dimensionless frequency 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 S0>8.

往复滑动接触温差引起的传热行为。

为了研究不同体积温度和滑动往复运动的两个接触块的两个粗糙表面之间的传热特性，采用二维传热模型分析无量纲平均热通量，考虑接触热导。给出了一系列模拟的结果，涵盖了广泛的操作参数，包括无量纲振幅 S~0、无量纲频率 ω~ 和界面电导测量 Ψ。结果表明，无因次平均热通量随着无量纲频率和幅值的增大而增大，且在 Ψ 较低范围内急剧上升，当 Ψ>71,500 且 S0>8 时，无因次平均热通量接近稳态。
