摘要
在一系列假定条件下,建立了一个低渗透非达西气体渗流的非线性移动边界偏微分方程数学模型,在理论上论证模型解的存在唯一性基础上,用对数网格对求解区域进行剖分,建立显式预测隐式校正格式,进而讨论模型的算法。此模型和算法具有一定的应用价值。
To establish the nonlinear partial differential equations' model for gas percolation flow through porous media of low permeability and on the basis of theory reasoning for existence and uniqueness of the model's solution,this paper makes use of logarithm gridding to partition the area of solutions,ulteriorly to establish discrete format of the model and to solve it.The model and the solution have some applicable values.
