Uniform Convergence of the Scattering Angle Function in Gas Mixtures.

The paper analyzes the uniform convergence in terms of the parameters of the scattering angle function of interacting molecules. This function is a key function from molecular kinetic theory and is used in computational technologies for determining the media transfer coefficients by the Chapman–Enskog method. The analysis will make it possible to reasonably determine the calculated values of transfer coefficients in gas mixtures in two-level numerical modeling of gas dynamics problems, which combine a description of macroprocesses based on macro-equations of heat and mass transfer with a micro description based on the Boltzmann equation.
