Abstract

If two rough surfaces slide against each other, the typical contact event is a transient interaction of a pair of asperities. A recent finite element solution of the heat conduction through such a contact is used to develop an expression for the heat transferred between the bodies as a function of the surface statistics, the nominal contact pressure and the sliding speed. Simple curve fits are provided to permit these results to be implemented as a macroscopic heat transfer condition in numerical simulations.
