The shock wave structure in one-component gas and in binary gas mixture

The variational method of solving Boltzmann equations, showing the forms of functionals, trial functions (generalized Mott-Smith distribution functions) and Euler equations for a single-component gas as well as for a mixture of gases, is considered. The details concerning the calculations of collision integrals, especially the dynamics of molecular collision, are discussed. The numerical characteristics of shock wave structures are considered. Relaxation parameters are also considered. Numerical methods used in the calculations, in particular the methods of solving Euler equations, are dealt with. The results relating to the shock wave structures in a single-component gas and in a binary gas mixture are discussed. The relation between the dimensionless shock wave thickness and Mach number in front of the shock wave is considered.
