The present paper studies complex nonequilibrium flows on the basis of the kinetic equations taking into account chemical reactions. Both slow and fast (for which mechanical and chemical relaxation time are of the same order of a magnitude) chemical reactions are considered. Our work is directed towards studying 1D and 2D Nonuniform Relaxation Problems (NRP). The algorithm for numerical simulations in the gases with chemical reactions is implemented within Unifiied Flow Solver (UFS). Flows with the ordinary and anomalous transport properties are investigated for several variants of chemical reactions parameters. A special attention is paid to consideration of the entropy. Comparison of the local magnitudes of nonequilibrium and equilibrium entropy is performed. The value of nonequilibrium entropy provides a characteristics of the complexity of these open systems. This study is focused on nonequilibrium processes keeping in mind simulation of flows in real natural systems.
