Experimental Investigation on Subcooled Boiling Heat Transfer in a Vertical Double-face Heated Narrow Annulus
【摘要】 在压力0.84~6.09 MPa、质量流速41.9~300.2 kg/(m2·s)、热流密度2.61~114.41 kw/m2范围内,以去离子水为工质,对间隙为1.5 mm环形窄通道实验段竖直向上流动的欠热沸腾传热特性进行了实验研究,得出了适用环形窄缝通道的欠热沸腾传热经验关系式。
【Abstract】 Experimental investigation on the subcooled boiling heat transfer was carried out in a vertical up-flow double narrow annulus with 1. 5 mm gap. The working fluid is deionized water. The ranges of parameters as follows: pressure 0. 84-6. 09 MPa, mass flux 41. 9-300. 2 kg/(m2?s) , heat flux 2. 61-114. 41 kW/m2. An empiric correlation used to predict the heat transfer of subcooled boiling in narrow annulus is induced from the experimental data.
