摘要: 建立了油气层酸化过程中的动边界模型,经Landau变换后,将所求问题转化为定边界上的非线性抛物型方程初边值问题和常微方程的初值问题的藕合问题,并给出了藕合问题的全离散格式。

关键词: 动边界问题, 辐合问题, 全离散格式

Abstract:

In this paper, a moving-boundary problem occurring under the acidifying was discussed, which was transformed into a coupled piroblem of an initial-boundary value problem of nonlinear parabolic equation and an initial value problem of di13'erential equation. Then, the full discrete scheme was given.

Key words: moving--boundary problem, coupled prob-lem, full discrete scheme
