为探究纤维过滤介质中纤维曲率对其内部速度分布、压力损失、过滤效率的影响,通过Digimat建模软件建立曲率K分别为0、2、4、6,固体体积分数为8%,在三维空间中随机分散排列的纤维过滤介质模型,结合计算流体力学方法,基于拉格朗日离散模型和Laminar流场,利用雷诺相似准则,设置入口速度分别为0.05、0.142、0.5、1、2 m/s,平均颗粒粒径为0.25、0.5、1、1.5、2.5、4、5 mm,对微米纤维模型内部气-固两相流动情况进行数值模拟。结果表明:随着纤维曲率K由0增大至6,在入口速度为0.5 m/s时,纤维曲率对速度场分布的影响不明显,速度场的分布呈无规律性;纤维曲率对模型内部压力损失有显著影响,随着纤维曲率的提高,纤维模型内部压力损失呈线性增大;纤维过滤介质的过滤效率随纤维模型曲率的增大而提高,在入口速度为1 m/s、模型曲率K为6时,对平均粒径为5 mm的颗粒过滤效率接近90%,明显高于相同粒径下K为0时的过滤效率。
