关于多孔介质中渗流的基本规律

ON BASIC LAW GOVERNING FLUID FLOW THROUGH POROUS MEDIA

达西定律作为渗流力学的一项基本规律,曾得到广泛的应用,但它只适用于线性的层流情况。本文简要回顾了非线性流及紊流的研究现状,并采用一种多数研究者公认的基本规律,建立了非线性流及紊流的运动方程式,它对研究高速渗流、气体渗流以及边界效应和离子效应等情况是有用的。

Darcy's law has achieved vast application as a basic law in problems of fluid flow through porous media. It, however, only holds for cases of linear, laminar flow. After making a brief review of the state-of-the-art on non-linear and turbulent flow studies, a system of equations of motion governing non-linear flow is established in this article, on the basis of one form of basic law supported by many investigators. These equations would be useful for studies of such cases as high velocity flow, gas flow, boundary ef-, fect, ion exchange effect, etc.
