摘要
对窄环隙内强迫对流换热特性进行了实验研究。实验结果表明,在紊流区窄环隙可以强化换热;当Re<150时,发生传热恶化。对窄环隙内加热流体和冷却流体强迫对流换热特性进行分析,可以为窄环隙内对流换热的进一步研究提供基础。
Experiments are carried out to study the convective heat transfer characteristics in narrow annulus. The results show that the narrow annulus can enhance heat transfer in the turbulent flow area. When the Reynolds number is lower than 150, the heat transfer deteriorates. The analyses of the heat transfer characteristics for the heating liquid and cooling liquid flowing through annulus are made to provide the basis for further studies.
