对液体膜在垂直涂覆管上的流动进行了实验研究。提出了一种新的热示踪技术，用于测量涂覆管上液膜的混合效果和液膜下落速度。总的来说，溶液的混合可以刷新大块液体的界面，从而使液膜内的传热更有效。利用高速摄像机和热成像技术，实验研究了液膜在涂覆分管上的流动规律和混合效应。流动显示实验表明，液膜在垂直涂覆区域的上边缘形成分叉流动。分岔流的汇合导致了更强的混合，使得热示踪液颗粒从界面向液膜内部移动。涂覆后的分管表面温度分布发生变形。涂覆分管的平均混合强度约为裸黄铜分管的1.2倍。
Experimental investigations have been carried out for liquid films flowing on the vertical coated division tube. A new thermal tracing technique was developed to measure the mixing effect and liquid film velocity of falling liquid film on the coated division tube. In general, mixing of solution could refresh the interface of bulk liquid, and hence lead to the more efficient heat transfer within the liquid film. By using the high speed video camera and thermal imaging technique, the flow patterns and mixing effect of liquid film on the coated division tube were investigated experimentally. Flow visualization experiments revealed that the liquid film formed a bifurcate flow at the upper edge of the vertical coated regions. The bifurcate flow converged and resulted in stronger mixing that drove the thermal tracing liquid particles from the interface to the internal of liquid film. There was deformation of temperature distribution on the coated division tube. The average mixing intensity on the coated division tube was about 1.2 times larger than that on the bare brass tube.
