This project is an experimental and modeling study of the flow of thin liquid films over complex, textured surfaces of the type suggested for use in ordered gas-liquid contactors. Such a surface might be a wire gauze or corrugated sheet. Attention will be directed at the influence of surface geometry, flow rate, and fluid properties on the formation and stability of dry patches. Modeling will attempt to relate fluid flow phenomena on the "microscopic" or gauze wire scale to the larger scale flows over the packing as a whole. Ordered packing offers some advantages over conventional random packings for gas-liquid contacting. The efficiency of contacting is determined in part by the liquid flow patterns.

该项目是一项实验性的建模研究，对薄液膜的流动在复杂的，纹理的表面上，该类型的类型是有序的气液接触器。 这样的表面可能是金属丝纱布或瓦楞纸板。 注意将指向表面几何形状，流速和流体特性对干斑的形成和稳定性的影响。 建模将尝试将“微观”或纱布线尺度上的流体流量现象与整个包装上的较大尺度流相关联。 订购的包装提供了与常规随机包装相比，用于气体液体接触的一些优势。 接触效率部分由液体流量模式确定。
