摘要 对于两相渗流驱动问题 ,模型表现为耦合的非线性微分方程组 ,一个是压力方程 ,形式为椭圆型 ;另一个是饱和度方程 ,形式为抛物型 .在一般的三角形剖分上提出了体积有限元 ,一般情况下可得到H1 -模的误差估计 ,利用一种特殊的对称对偶剖分 ,可以得到L2 Two phase, incompressible flow in a porous medium is governed by a system of nonlinear partial differential equation. A finite volume method on triangular subdivisions is presented and analyzed. Under special symmetric volumes optimal order error estimate is derived. A numerical experiment is presented.
