摘要：
In this paper, we carry out the error analysis for a totally decoupled, linear and unconditionally energy stable finite element method to solve the Cahn-Hilliard-Navier-Stokes equations. The fully finite element scheme is based on a stabilization for Cahn-Hilliard equation and projection method for Navier-Stokes equation, as well as the first order Euler method for time discretization. A priori error analysis for phase field, velocity field and pressure variable are derived for the fully discrete scheme.(c) 2022 Elsevier Inc. All rights reserved.
