Velocity slip and temperature jump coefficients for gaseous mixtures. IV: Temperature jump coefficient. (English) Zbl 1189.76453
Summary: The temperature jump coefficient was calculated for a binary gaseous mixture on the basis of the McCormack kinetic model of the Boltzmann equation, which was solved by the discrete velocity method. The calculations were carried out for the three mixtures of noble gases: neon-argon, helium-argon and helium-xenon. A strong influence of the intermolecular interaction on the temperature jump coefficient was observed by comparing the results based on the model of rigid spheres with those obtained for a realistic potential.
