On the Velocity Non-Equilibrium for Two-Phase Flow Computations

Résumé

A fully hyperbolic and fully conservative mixture conservation laws that treat the relative motion in gas-liquid two-phase flows is presented. These laws are based on compressible gas-liquid two-phase flow with velocity and pressure non-equilibrium. The resulting theoretical model accounts for the interaction between the gas and liquid phases with more reasonable physical meaning. Within this framework, the distinctness of the model conservation laws enables a straightforward extension and application of single-phase fluid dynamics numerical methods. Computations are carried out and presented. It is found that the interfacial friction source term has a strong influence on both the parameters and the wave structure in non-equilibrium two-phase flows.
