In many applications, a temperature of fixed cross section of micro-tube is not uniform, but it can deviate from its equilibrium value. In this case the gas flow is not axi-symmetrical any more, but the flow is two dimensional. Under such conditions, the density cannot be considered as uniform across the section and gas circulations can occur. The aim of the present work is numerical calculation of distributions of velocity, density and temperature caused by an azimuthal temperature distribution over the tube wall. The problem is solved on the basis of the kinetic equation over a wide range of the gas rarefaction.
