摘要
通过三维微观孔隙模型来评估碳纤维多孔介质中流体对材料结构和流体黏度的依赖性，并使用Python语言开发了一种新的多孔介质孔隙和骨架的分离方法。通过模拟发现，孔隙率对黏性阻力和惯性阻力起决定性的作用；黏度对惯性阻力的影响比对黏性阻力的影响大。
Abstract
In this paper,the dependence of high-speed fluid on material structure and fluid viscosity in carbon fiber porous media is evaluated by three-dimensional microscopic pore model,and a new method for separating pore and skeleton in porous media is developed by means of Python.It is found by simulation that porosity plays a decisive role in viscous resistance and inertial resistance.Viscosity has a greater impact on inertial resistance than viscous resistance.
