*讲座内容简介：

In this talk, I will first present the mixed DG method for the coupled Stokes-Darcy problems. The method invokes the stress-velocity formulation of the Stokes equations, where the symmetry of the stress is strongly imposed. The staggered DG method is used to discretize Darcy equations. As such, the discrete formulation can be easily adapted to account for the Beavers--Joseph--Saffman interface conditions without introducing additional variables. Then, I will present the development of the Robin-type domain decomposition method for the coupled Stokes-Darcy problem, where the Stokes subproblem and Darcy subproblem are solved sequentially. Several numerical experiments will be presented to illustrate the performance of the proposed scheme.
