摘要

在目前的工作中,模拟进行了数值表征多孔材料。控制这个问题的基本方程是纳维-斯托克斯方程和达西方程的结合。为了理解利害关系的现象,首先完成了对网格与数值解的独立性的第一次测试,第二次测试致力于验证Darcy (Re <<1)。材料的表征是基于物理测试;第一个用于研究材料的孔隙率,第二个用于研究材料的厚度,第三个用于研究材料的饱和度。结果一方面给出了速度场和流线的轮廓,另一方面用曲线来解释所研究的物理参数之间的关系。

Modeling and characterization of a porous medium by a coupled approach between the Wavier-Stokes and Darcy equations
In this present work, simulations were carried out numerically to characterize a porous material. The basic equations, which govern this problem, are those of the Navier-Stokes equations coupled with the Darcy equation. In order to understand the phenomena at stake, a first test was first completed on the independence of the mesh compared to the numerical solution obtained, the second test is devoted to the validation of Darcy (Re <<1). The characterization of the material is based on physical tests; the first is devoted to the porosity of the material, the second to the thickness, and the trireme to the saturation. The results are presented on the one hand contours for the velocity fields and streamlines, and on the other hand, are illustrated with curves to interpret the physical parameters studied in relation to each other.
