A transient flash temperature model was developed based on a Fast Fourier Transform method. An analytical expression for the heat partition function was obtained. Together, these substantially increase the speed of flash temperature calculations. The effect of surface topography on the flash temperature was examined. According to the simulation results, the surface with a longitudinal roughness produced a noticeably higher flash temperature than the surface with a transverse roughness. The simulation results also indicate that there is a significant cross-heating activity between the asperities; the temperature profiles appeared surprisingly gradual although their contact pressures had extremely sharp peaks.
