Title:
The conservative S-DDM schemes for multicomponent contamination flows

Abstract:
Since the non-overlapping domain decomposition methods have the advantages in the computational and communication costs in parallel computing, some explicit/implicit non-overlaping domain decomposition methods have been developed in solving time dependent PDEs. However, these methods break the important physical law of mass conservation over the whole domain. In this talk, I will first present our recent development and analysis of the conservative splitting domain decomposition methods for parabolic equations and for convection diffusion equations. I will then present numerical simulations of the multicomponent contamination flows in porous media by the developed methods. I will also discuss how to study the conservative DD methods for the atmospheric envirionmental computation.
