多孔介质的流体流动分析在广泛的工业应用中非常重要，包括但不限于树脂转移成型、过滤器分析、地下水和污染物的输送以及碳氢化合物的回收。渗透率可能是表征多孔介质最重要的性质；然而，由于其对介质孔隙结构的复杂依赖，对不同类型多孔介质的测定具有挑战性。本文采用晶格玻尔兹曼方法模拟了三维随机纤维介质中的流体流动。我们利用达西定律确定了介质的渗透率，在很大的空隙分数范围内(0.08
Fluid flow analyses for porous media are of great importance in a wide range of industrial applications including, but not limited to, resin transfer moulding, filter analysis, transport of underground water and pollutants, and hydrocarbon recovery. Permeability is perhaps the most important property that characterizes porous media; however, its determination for different types of porous media is challenging due its complex dependence on the pore-level structure of the media. In the present work, fluid flow in three-dimensional random fibrous media is simulated using the lattice Boltzmann method. We determine the permeability of the medium using the Darcy law across a wide range of void fractions (0.08
