Ivanov D.V., Kobelkov G.M., Lozhnikov M.A., and Kharisov A.F.

This paper is devoted to the numerical solution of the dynamics equations for a viscous heat-conducting compressible gas by the method of adaptive viscosity on unstructured tetrahedral meshes. A combination of the MacCormack method and the Lax-Wendroff method allows one to monotonize the difference scheme using the method of frozen coefficients. The numerical results are in good agreement with experimental data.

Keywords: numerical simulation, gas dynamics, unstructured meshes, artificial viscosity.
