中文摘要：
二阶段的流动的一个数学模型和一个物理模型二维(2D ) 为板类型的垂直的节组织了收拾行李的 Mellapak 250 .Y 被建立并且验证。模型被用来在液体电影的连续性和液体劫盗的数量上学习包装表面微观结构的影响。模拟结果证明圆角落形状和微起浪的结构在仍然是液体电影的连续性并且增加液体劫盗的数量是有利的。适当液体流动率被调查不同液体装载在收拾行李的表面上获得一部未破损的液体电影决定。为煤气的阶段的入口和插头之间的压力差别允许气体和液体在 2D countercurrently 流动计算领域。煤气的流动的方向变化发生在阶段接口区域附近。
英文摘要：
A mathematic model of two-phase flow and a physical model of two-dimensional （2D） vertical section for the plate-type structured packing Mellapak 250.Y were set up and verified. The models were used to study the influence of packing＇s surface microstructure on the continuity of liquid film and the amount of liquid holdup. Simulation results show that the round corner shape and micro wavy structure are favorable in remaining the continuity of liquid film and increasing the amount of liquid holdup. The appropriate liquid flow rate was determined by investigating different liquid loadings to obtain an unbroken liquid film on the packing surface. The pressure difference between inlet and outlet for gas phase allowed gas and liquid to flow countercurrently in a 2D computational domain. The di- rection change of gas flow occurred near the phase interface area.
