Transport processes at part accommodation by the walls of a rectangular channel
O. V. Germider, V. N. Popov Northern (Arctic) Federal University named after M. V. Lomonosov, Arkhangelsk
Abstract:
The article considers a flow of rarefied gas with specular-diffuse reflection of gas molecules from the model of rectangular cross section of the channel walls in the free mode. We assume that the channel is maintained constant pressure gradient value. The mass and heat flow as a function of tangential momentum accommodation coefficient and the ratio of linear dimensions of the channel cross section are obtained. A comparison with analogical results presented in the open data is done.
Keywords:
specular-diffuse reflection model, rarefied gas, free-molecular regime.
