AnnotationThe article describes a numerical algorithm for solving the system of NavierStokes equations for a multicomponent gas mixture by the Discontinuous Galerkin Method on AMR. The implementation of the constructed scheme is based on the data structure and algorithms of the p4est library. The results of solving such problems as the flow around an NACA 0012 airfoil, the multimaterial triple point problem, and the problem of the development of the Richtmyer-Meshkov instability are presented
