| 摘 要： | 对不同纤维体积分数和不同纤维分布状态的纤维模型进行数值模拟,分析纤维微结构的改变对流体流动行为的影响.结果表明,在纤维体积分数低时,纤维间最小距离对平均渗透率影响小;在纤维体积分数高时,平均渗透率随着最小距离的减小而减小.研究渗透率标准偏差与最小距离、体积分数三者关系,在纤维体积分数低时,渗透率的标准偏差主要由最小距离...

| Abstract: | The effect of the fiber microstructure on the fluid flow behavior was investigated.Simulations on the fiber models which have different fiber volume fractions and nearest inter-fiber spacing were performed to calculate the fiber permeability.The results reveal that the permeability is less sensitive to the nearest inter-fiber distance when the volume fraction is low.At the high volume fraction,the permeability declines with the decrease of the nearest inter-fiber spacing.The relation of permeability standar... |
