In this paper, we propose a new generalization of the well-known Cahn–Hilliard two-phase model for the modeling of n-phase mixtures. The model is derived using the consistency principle: we require that our n-phase model exactly coincides with the classical two-phase model when only two phases are present in the system. We give conditions for the model to be well-posed. We also present numerical results (including simulations obtained when coupling the Cahn–Hilliard system with the Navier–Stokes so as to obtain a phase-field model for multiphase flows) to illustrate the capability of such modeling.

Lattice Boltzmann Scheme

A new type of a lattice phase-field model is developed and coupled with the lattice Boltzmann method to compute the soldification influenced by convection. Two methods of treating the solid-fluid interaction within the lattice Boltzmann scheme are tested.
