Journal of Engineering Thermophysics Aims and scope

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.
