摘要: 本文以水和粘性液体为工质,对环隙宽度为2mm的环隙内流动沸腾传热特性进行了研究.实验结果表明,在一定的热通量范围,环隙内流动沸腾传热系数较空管的平均提高80%,总传热系数平均提高60%.当以水为工质时,总传热系数的实验值与计算值吻合较好.
Abstract: In this paper the characteristics of flow boiling heat transfer in an annu-lus 2mm in width have been studied by using water and viscous liquid. The experimental results show that within a certain range of heat flux the flow boiling heat transfer coefficient in an annulus is larger than an empty tube by 80 %; the overall heat transfer coefficient is increased on an average by 60%. The calculated value of overall heat transfer coefficient is compared with the experimental value with water as the boiling liquid.
