| 摘 要： | Two phase ,miscible,incompressible flow in porous media is governed by a system of nonlinear partial differential equations. Many numerical methods have been given by didierent authors to this system,hut these methods need very high regularity conditions. Actualty,in most practical applications these regularity conditions couldn‘t be satisfied. In this paper,the problem of discontinuous coefficients with lower regularity conditions is considered and the error estimates are demonstrated.

| Abstract: | . Two-phase
,miscible,incompressible flow in porous media is governed by a system of nonlinear partial
differential equations.Many numerical methods have been given by different authors to this
system,but these methods need very high regularity conditions.Actually,in most practical
applications these regularity conditions couldn't be satisfied.In this paper,the problem
of discontinuous coefficients with lower regularity conditions is considered and the error
estimates are demonstrated. |
