An explicit iterative scheme for 3D multicomponent heat conducting flow simulation

This paper presents the development and testing of time integration scheme for system hydrodynamic equations gas mixture. These take into account phenomena multicomponent diffusion heat transfer. The governing equation is discretized by finite volume approach on three-dimensional unstructured grids. According to algorithm, computation any single step split sequence hyperbolic parabolic stages. subtask solved using Godunov-type scheme. explicit iterative Chebyshev scheme, which algorithmically simple does not involve tuning parameters. stage addresses dissipative fluxes (viscosity, thermal conductivity). number iterations determined convective upper bound discrete operator. resulting ensures fulfillment conservation laws at level. computer code can be used in highly parallel computing large-scale simulation. proposed recommended applied problems processes are close interaction, particularly plasma physics astrophysics.
