Study on Mist Cooling for Heat Exchangers: 3rd Report, Development of High-Performance Mist Cooled Heat Transfer Tubes

摘要

In order to pursue a high-performance mist-cooled heat exchanger, development of heat-transfer tubes with various surface structures, such as grooved, wire-wound, and screen mesh wrapped tubes, has been performed on the basis of the previous results of smooth surface tubes. The effect of surface structures on heat-transfer enhancement was clarified experimentally and theoretically with relation to the extension of a wetted area.
