HYPERBOLIC MODEL OF A ONE-VELOCITY VISCOUS HEAT-CONDUCTING MEDIUM

A modifi ed, generalized-equilibrium model of a one-velocity heterogeneous medium is presented, which accounts for the viscosity and thermal conductivity of the mixture, as well as for interfractional heat transfer. A characteristic analysis of the model′s equations has been carried out, and their hyperbolicity is shown. A description is given of Godunov′s method with a linearized Riemann solver intended for calculating mixture fl ows on curvilinear grids, with the use of which a number of problems for a vapor–air mixture has been investigated.
