An approximate model of multicomponent two-phase flow with partial miscibility
Abstract:
A new approximated model of multi-component two-phase flow is proposed. This model is based on the thermodynamically consisitent model of multi-component two-phase diffuse interface flow and additional assumption that the interface thickness is much smaller than all other length scales. The thermodynamically consisitent model of multi-component two-phase diffuse interface flow in its turn is based on the components mole amounts and momentum conservation laws, the linear non-equilibrium thermodynamics relationships and square gradient Helmholtz free energy form.
