We study the structure of a shock wave for a two-, three- and four-componentgas mixture on the basis of numerical solution of the Boltzmann equation forthe model of hard sphere molecules. For the evaluation of collision integralswe use the Conservative Projection Method developed by F.G. Tscheremissinewhich we extended to gas mixtures in cylindrical coordinates. The transitionfrom the upstream to downstream uniform state is presented by macroscopicvalues and distribution functions. The obtained results were compared withnumerical and experimental results of other authors.
