二、講座信息 In this talk, we will first introduce the conservation laws of contamination flows and the coupled nonlinear PDEs for describing contamination flows. We will then present our development of efficient domain-decomposition schemes for solving convection diffusion problems and parabolic problems and for solving contamination flows in parallel computing. We will also present block-centered compact difference methods for solving the time-dependent partial differential equations and report the block-centered compact S-DDM scheme. Numerical experiments are given to show their performances. The developed algorithms work efficiently over multiple sub-domains, which can be applied in simulation of contamination flows. 時(shí)間：2023年5月26日14:00-15:00 地點(diǎn)：數(shù)學(xué)院424會(huì)議室
