Quasi-Hydrodynamic Model of Multiphase Fluid Flows Taking into Account Phase Interaction

Аннотация

A quasi-hydrodynamic system of equations describing flows of a heat-conducting viscous compressible multiphase multicomponent fluid is constructed taking into account surface effects. The system was obtained by generalizing the methods of obtaining a single-phase quasi-hydrodynamic system and a multicomponent flow model with surface effects based on the concept of microforces and microstresses. The equations are derived using the Coleman–Noll procedure. The results of the simulations show that the constructed model is applicable for modeling multiphase multicomponent flows with allowance for surface effects on the interfaces.
