摘要 对多孔纤维材料中流体渗流的特性进行了分析.根据特定初始条件和边界条件,推导出了温度和压强的解析模型,分析了棉和涤纶两种纤维材质中液体渗流压强随着时间的变化趋势.通过对比多孔材料中流体温度的计算结果与实验结果,验证了模型的有效性和实用性. In this paper, the characteristics of fluid in porous fibrous material are analyzed, and the analytical expression of the temperature and pressure are derived according to the specific initial and boundary conditions. The pressure changes of liquid in cotton and polyester fiber material are contrasted in figures. Through the contrast of the computed results and the experimental results of the temperature, the validity and practicability of the model was verified.
