Testing and numerical modelling of multicomponent filtration with mass interchange

The work is devoted to developing and testing of numerical modeling of multicomponent filtration with intensive mass interchange between phases. Self-similarity solutions of equations are described. The special state equation is offered to receive curves of dew and boil, and also other thermodynamic functions in an analytical view. The equation is of interest for modeling of shocks and instabilities, bounded with phase transitions. It is offered the analog of entropy correction for TVD-schemes to avoid unphysical solutions.
