摘要：

Flow of diatomic rarefied gas in capillary of infinite length with circular cross section caused by small pressure gradient (Poiseuille flow) and/or small temperature gradient (thermal creep flow) is studied numerically on the basis of kinetic model taking into account rotational degrees of freedom of molecule (R-model). The main quantity calculated is the flow rate through capillary cross section. The results are compared with that obtained on the basis of the kinetic S-model.
