| Summary: | The work is devoted to developing and testing parallel algorithms, suit of computer programs for numerical solution of CFD-problems on modern supercomputers. The paper summarizes our experience in solving various practical problems of gas dynamics. These problems include research of gas flow around bodies of complex shape by viscous gas flows with radiation processes near the surface of the bodies, calculations of jet streams in the open space and flows in micro channels of technical systems. We have developed approaches combining unstructured grids, domain decomposition technique, parallel implementation via MPI technology, OpenMP, CUDA. Calculations are performed on the heterogeneous computer systems with Graphical Processing Units, classical microprocessors (Central Processing Units) and use advanced parallel approaches.
