New hyperbolic models of dusty gas flow

Abstract

The paper presents hyperbolic models for dusty gas flow formulated for single- and multivelocity approximations with account for inter-fractional heat transfer. Characteristic analysis of equations for the model was performed. The Godunov method and linearized Riemann solver was applied for a solution on curvilinear mesh: the Prandtl−Meyer problem for air-droplet mixture was solved. The simulation results were compared with the self-similar solution.
