Firstly, the characteristic finite element method, the characteristic mixed finite element method and the characteristic expansion mixed finite element two-grid algorithm for the incompressible miscible displacement problem are presented. Then, the characteristic finite element two-grid algorithm for the compressible miscible displacement problem is discussed. Numerical examples are given to illustrate the effectiveness of the two-grid algorithm. Finally, the direction of further research on the two-grid algorithm for miscible displacement problem is discussed %K 非线性渗流耦合问题 %K 特征有限元 %K 混合有限元 %K 两层网格算法 %K < %K br> %K nonlinear coupled miscible displacement problem %K characteristic finite element method %K characteristic mixed finite element method %K two-grid algorithm %U http://journal.scnu.edu.cn:8080/jwk_xbzrb/CN/abstract/abstract4486.shtml
