摘要：
Finite element results are presented for the total heat exchange between two asperities on opposing sliding rough surfaces during a single transient interaction. Results are also presented for the corresponding maximum (flash) temperature. Dimensional analysis shows that the results can be expressed as functions of a single dimensionless parameter, the asperity Peclet number. This numerical data is closely approximated by simple algebraic expressions, permitting the results to be used in statistical treatments of the rough surface sliding contact problem, based on asperity models.
