报告摘要:We present a second order in time accurate and efficient numerical scheme for the Cahn-Hilliard-Navier-Stokes system that models two-phase flows. Our efficient algorithm is based on the Chorin-Temam projection method for the velocity equation and the convex-splitting method for the phase field (Cahn-Hilliard) equation. The scheme inherits the energy law of the original system and is uniquely solvable at each time step. A similar idea can be applied to the Cahn-Hilliard-Darcy system that models two-phase flow in a Hele-Shaw cell or in porous media.
