Abstract

Simulations of flows on the basis of kinetic equations for mixtures with chemical reactions are performed. The nonuniform relaxation problems are solved for different variants. The numerical methods of unified flow solver are used for simulation of 1D and 2D flows with nonequilibrium boundary conditions. The kinetic approach provides results, which are beyond the traditional theory of macroscopic phenomena based on the Navier-Stokes equations. Nonequilibrium flows with anomalous transport properties in relaxation zones are described. A special attention is paid to study of behavior of the nonequilibrium entropy for 1D and 2D cases both for slow and fast chemical reactions and to investigation of it as a measure of complexity of open systems.
