Shocks and Discontinuities Treatment in Multi-species Flows Using a Riemann Solver

The diversity of industrial configurations presenting a flow mixtures several species calls on researchers to develop reliable, easily usable tool capable treating this type in the presence an interface. present work contributes numerical solution multi-species equations shocks and contact discontinuities. A shock capture-type method based separation roe flux differences is associated with two-parameter equation state. results presented here show that model has ability correctly capture discontinuities provide accuracy compatible requirements zones discontinuity existing flow.
