摘要
研究多孔介质中可压缩渗流问题数值算法，压力方程用混合元方法，饱合度方程用沿特征线修正的有限元方法，构造了全离散数值计算格式，证明了最优Ｈ１模误差估计．
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.
