內(nèi)容摘要：
Groundwater environment computation is an important and difficult problem. Mathematical models describing multi-component pollution flows in porous media are the time-dependent and coupled nonlinear partial differential equations. Due to the complexity, the nonlinearity, and the large scale and long term of simulation and protection, it is important to develop efficient numerical methods for solving multicomponent pollution flows in parallel computing. In this talk, I will present our conservative S-DDM method that we develop for computing nonlinear multicomponent contamination flows in porous media over multiple non-overlapping domain decomposition. The significant feature of our scheme is that while it keeps the excellent advantages of the non-overlapping domain decomposition and the splitting technique, the developed algorithm conserves mass over the whole domain. Numerical experiments show the excellent performance of our proposed conservative method for computing nonlinear multicomponent pollution flows in environmental computation.
