Abstract: In the framework of the kinetic approach, we construct an analytic solution (in the form of a Neumann series) to the problem of the thermal slip of a gas along a rigid flat surface. As the basic equation, we use the linearized ellipsoidal statistical model of the Boltzmann kinetic equation, and as boundary conditions on the streamlined surface we take the mirror-diffuse reflection model. For the various values of the accommodation coefficient of the tangential momentum of the molecules of the gas, we compute the velocity of the thermal slip of the gas along the surface and find the distributions of the gas velocity and the heat flow vector. A comparison with similar results available in the previously published works is made.

Keywords: Boltzmann kinetic equation, model kinetic equation, boundary condition model, exact analytical solution.
