Model for multiphase fluid flows with interphase interaction taken into account

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 taking into account the surface effects based on the concept of microforces and microstresses. The equations are derived using the Coleman–Noll procedure. The results of the calculations show that the constructed model is applicable for modeling multiphase multicomponent flows with allowance for surface effects on the interfaces.
