Code for relative permeabilities for two-phase flow between parallel plates with slip conditions

This MATLAB code calculates relative permeabilities of two fluids flowing between two parallel plates, depending on their viscosities, saturation and boundary conditions at the top and bottom plates. The underlying assumptions behind the derivation are shown in the pdf "overview_relativepermeabilities.pdf", where also the resulting equations are listed. The matlab file "relativePermeabilities.m" performs the actual calculation of the relative permeabilities, for given saturation, viscosities of both fluids and slip lengths at the boundaries. The matlab file "example_usage.m" shows an example of how to use "relativePermeabilities.m".

本 MATLAB 代码针对两种流体在两平行板间流动时的相对渗透率进行计算，该计算依赖于流体的粘度、饱和度以及上下板的边界条件。推导过程中的基本假设展示于名为“overview_relativepermeabilities.pdf”的 PDF 文件中，其中亦列出了所得方程。名为“relativePermeabilities.m”的 MATLAB 文件负责执行相对渗透率的实际计算，所需参数包括给定的饱和度、两种流体的粘度和边界处的滑移长度。名为“example_usage.m”的 MATLAB 文件提供了一个使用“relativePermeabilities.m”的示例。
