Original Papers


Numerical calculations of heat transfer between two coaxial rotating cylinders at a small temperature difference are carried out over wide ranges of the Knudsen number and the angular velocity. The calculations have been performed based on the S-model of the Boltzmann equation by the discrete velocity method. It has been confirmed that in a rotating gas a radial temperature gradient causes both radial and tangential heat fluxes. Also, it has been found that the radial heat flux is affected by the rotation.
