摘要
提出了解不可压缩两相混溶驱动问题的一种新的数值方法 ,压力方程用混合有限元求解 ,浓度方程用差分流线扩散方法求解 .在空间方向采用SD方法离散 .对时间方向进行差分离散 (如Eu ler向后离散 ) ,并给出了L2 -模误差估计 .
A new numerical method is studied for incompressible miscible displacement in porous media.The pressure equation is solved by mixed finite element method,while the concentration equation is solved by finite difference-streamline diffusion finite element method,that is,using SD F.E discrete only inspace variables and using finite difference discrete in time(e.g.backward difference Euler-method).The error estimate in L 2-norm is erived.
