In this talk we will present some MAC finite difference methods (finite volume methods) on staggered grids for some flow problems, including the non-Darcy flow in porous media and wormhole propagation, the Stokes and Navier-Stokes flow, where the velocity and pressure are approximated in differential grid points. We will also give the MAC scheme for Stokes and Navier-Stokes problems, non-Darcy problems, Coupled Stokes-Darcy problems,….The approximate schemes, existence and uniqueness of the solutions, convergence, superconvergence and numerical examples will be presented.
歡迎廣大師生參加！
