本文严格按照实验程序,系统地研究了核沸腾传热受射流速度大小、液体流动方向、喷嘴直径和液体过冷度等因素的影响。实验结果表明:核沸腾传热曲线随过冷度增加而向左移动,与其它因素无关。池核沸腾和冲击核沸腾曲线可用同一关联式表达。对高速射流冲击驻点的核沸腾曲线及其过冷度进行了修正,使前者向左移动,而后者增加。
According to rigorous procedures, an experimental study was performed to investigate the effects of jet velocity, flow direction, nozzle diameter and fluid subcooling on fully developed nucleate boiling curves with impingement circular submerged jets of highly-wetting liquids in the paper. The experimental results showed that the high heat flux portions of heat transfer curves shifted to the left with elevating fluid subcooling and was independent of other factors. It can be expressed with a same correlatio...
