摘要
本文在一般的三角形剖分上对两相渗流驱动提出了全离散体积有限元 ,并分析了带有弥散项时格式的收敛性 ,得到H1 模的最优估计 .
Two-phase,incompressible flow in a porous medium is governed by a system of nonlinear partial differential equation.A finite volume method on triangular subdivision is presented and analyzed.The amount of computing work is smaller than that of finite element methods.Optimal order H1-error estimate is derived when dispersion is included.A numerical experiment is presented.
