Zusammenfassung:The roughness effects are not negligible in mixed lubrication regime. An average Reynolds equation using flow factors is useful to determine the effects of surface roughness on mixed lubrication. In this study, the effect of kurtosis on flow factors is investigated using random rough surfaces generated numerically. The results show that flow factors are very sensitive to h/σ according to the value of kurtosis in the partial lubrication regime.
