Abstract

This paper proposes flow factor for arbitrary Knudsen number considering accommodation factor. Numerical analyses of rarefied gas are conducted by using proposed slip model. An analysis model is a slider of HDD, which is one of the typical cases of rarefied gas regime. The slider surface is measured by a confocal laser microscope. And then we confirm the effect of surface roughness in rarefied gas regime.
