title: Hierarchical model in multiphase flow
abstract: A hierarchical model for two-phase flow is constructed. The model has two layered systems one corresponding to the macroscopic hydrodynamics described by the Navier-Stokes equation and the other to the interfacial dynamics described by the Cahn-Hilliard-type equation. Numerical simulations in some simple cases are carried out to examine the validity of the model. As an application of the model simulations of two colliding droplets under shear flow are presented.
