报告题目：Modeling and numerical analysis of compressible Darcy-Brinkman transport problem in fractured media
报 告 人：刘伟，鲁东大学
报告摘要：A hybrid-dimensional coupled model of compressible fluid flow in fractured porous media is studied from theoretical and numerical points of view, in which the flow is governed by Brinkman model in fracture and Darcy model in surrounding porous media. A new numerical scheme with the fewest nodal points is constructed for solving the hybrid-dimensional coupled model on non-matching grids. The second-order error estimates with respect to different meshsizes are derived for both pressure and velocity in corresponding discrete norms. Numerical experiments are performed to verify the efficiency and accuracy of the proposed method.
