A Combined Mixed Finite Element and Discontinuous Galerkin Method for Compressible Miscible Displacement Problem |
| |
| Abstract: | We consider a combined method consisting of the mixed finite element method for flow and the discontinu-ous Galerkin method for transport for the coupled system of compressible miscible displacement problem.A cut-off oper-ator M is used in the discontinuous Galerkin formular as the reference5].We can obtain the optimal priori error esti-mate for both cincentration and pressure. |
