摘要(Abstract)：

利用内部输水性材料作为波形除雾器壁面有利于液体传输，从而提升除雾性能。对该除雾器雾滴捕集率、液体传输速率及夹带抑制机理进行了研究，建立了预测雾滴捕集率的半经验模型和模拟计算方法，并得到实验验证，据此建立了内部输水性壁面降膜厚度与材料输水特性关联式，解释了材料内部输水性能对该除雾器的夹带抑制机理。模型计算表明，常规除雾器气速超过临界值4.82 m·s^-1时即会导致液膜剪切产生夹带，而内部输水性壁面除雾器接近该气速时壁面尚处于无液膜状态，气速超过临界值19.52 m·s^-1才开始产生液沫夹带，表明内部输水壁面能有效降低液膜厚度，且液滴在壁面完全铺展，抑制夹带发生，从而强化除雾器处理能力、提高分离效率。
