Copyright policy )Velocity slip and temperature jump coefficients for gaseous mixtures. II. Thermal slip coefficient
The thermal slip 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 potential of intermolecular interaction upon the thermal slip coefficient was observed by comparing the results based on the model of rigid spheres with those obtained for a realistic potential. An example of application of the thermal slip coefficient is given.
