Towards an efficient algorithm for the simulation of viscous two-phase flows with real gas effects
Résumé
A discrete equation method (DEM) for the simulation of compressible multiphase flows including viscous and real-gas effects is illustrated. A reduced five equation model is obtained starting from the semi-discrete numerical approximation of the two-phase viscous model. Then, a simple algorithm is proposed in order to use two different equations of state at the vapor and liquid-vapor conditions. Simulation results are validated with well-known results in literature. Potentialities in improving the quality of the numerical prediction by using a more complex equation of state are thus drawn.
