Abstract
This paper considers a flow of rarefied gas with a specular-diffuse reflection of gas molecules from a model of a rectangular cross section of channel walls in the free regime. We assume that the channel maintains a constant pressure gradient. Mass and heat flows are obtained as a function of the tangential momentum’s accommodation coefficient and the ratio between the linear dimensions of the channel’s cross section. Similar results presented in the literature are compared.
