The error analysis for the Cahn-Hilliard phase field model of two-phase incompressible flows with variable density

AIMS Mathematics, 2023
In this paper, we consider the numerical approximations of the Cahn-Hilliard phase field model for two-phase incompressible flows with variable density. First, a temporal semi-discrete numerical scheme is proposed by combining the fractional step method (
