| Abstract: | A numerical method is established for completely compressible miscible displacement in porous media. The pressure equation is discreted by mixed finite element,whilethe saturation equation is solved by finite element method combining with the modifiedmethod of characteristics. Optimal error estimate in HI norm is proved. |
