| 英文摘要 | Numerical simulation of microstructure coarsening is a subject of great interest in computational materials science. the coarsening dynamics in a binary mixture can be modeled by the celebrated cahn-hilliard equations. to perform efficient and accurate long-time integrations, we develop a fast and stable high order numerical method for solving cahn-hilliard equations. the spatial discretization is carried out by the compact central difference scheme with fft-based fast implementation while the time integration is done through the accurate exponential time differencing multistep approach. we demonstrate the effectiveness of the proposed method by numerical experiments and study computationally the coarsening kinetics corresponding to different choices of the diffusion mobility.
