Abstract

The paper presents an experimental study of heat transfer in a liquid rivulet flowing down a vertical heated plate under the action of gravity. With the use of the optical schlieren method and high-speed shooting, regimes of rivulet flow of liquid over a heated plate were visualized. By means of infrared thermography, the process of heat transfer between the rivulet of liquid and the plate was studied. The heat transfer coefficient was measured for the rivulet flow of intensely evaporating low-boiling liquid. The results obtained can be used in development of cooling systems for various heat-loaded equipment.

FC-72流体细流在加热垂直板上的传热实验研究

摘要

本文介绍了液体细流在重力作用下沿垂直加热板流动的传热实验研究。通过使用光学纹影方法和高速拍摄，可以看到加热板上液体的小溪流动状态。借助红外热成像技术，研究了液体细流与平板之间的传热过程。测量了强烈蒸发的低沸点液体的小溪流的传热系数。获得的结果可用于开发各种热负荷设备的冷却系统。
