Abstract: Purpose The purpose of this study is to propose a fractal model of thermal contact conductance of rough surfaces based on axisymmetric cosinusoidal asperity. Design/methodology/approach The effects of contact load, fractal dimension, fractal roughness and friction coefficient on the thermal contact conductance of rough surfaces were investigated in this study. Findings The findings suggest that as the contact load increases, the thermal contact conductance of rough surfaces also increases. In addition, an … Show more
