中文摘要：

针对编织类纤维增强体的纤维束之间与纤维束内孔隙的双尺度特点,建立了平纹织物的细观结构模型,并推导了汇函数的数学表达式。建立了局部细观流动特征的非饱和流动控制方程,利用有限元/控制体积方法求解,得到了局部饱和度分布。与实验进行比较,吻合较好。

英文摘要：

A micro-structure model for the double scale porous media was set up.An mathematical expression of sink function was derived.The governing equation for local unsaturated flow was obtained.The finite element control volume method was employed to simulate the unsaturated flow.Finally,the results from numerical simulations and experiments were compared,which agreed well.
