报告摘要：

This talk presents two industrial application projects: 1) Mathematical modelling and computational simulation of transient two-phase flows in pipelines of the nuclear power plant; 2) Multi-phase flow problems during the liquid composite molding (LCM) aerospace manufacturing processes, will be presented. These research projects which often involve contact and interface problems between fluids and structures, plus its multi-physical, multi-scale nature and complex system typologies, are known to be challenging, and necessitating continuous research effort. Motivated by these difficulties, some new numerical methods, e.g. the Conservative Flux Optimization methods (CFO) and the Simplified Weak Galerkin Methods (SWG) have been proposed and studied for some simplified problems. Numerical theories such as the stability, discrete maximum principle (DMP) and optimal order of error estimates have been established and verified by numerical experiments. These numerical methods will be further extended and applied to solve more realistic multi-physical problems.
