Abstract
The characteristics of momentum and kinetic energy transfer in rarefied gases are analyzed on the basis of the elementary kinetic theory of gases. The proposed formulas take into account the discreteness of the gas structure which, as is shown, is manifested in the presence of curvature of the heat-transfer surfaces. The validity of the formulas is confirmed by existing experimental data.
