摘要
本文以常压去离子水为工质,对自然循环工况下上升加热段内单相水的对流传热特性进行了实验研究。实验结果表明,自然循环工况下上升加热段内工质的物性变化及由浮升力引起的自由流动对对流传热特性有重要影响。通过分析,提出了计算自然循环工况下上升加热段内单相水的对流换热系数的经验关系式。
The investigation on heat transfer of single phase liquid flow in a tube with natural circulation is performed. The experimental results indicate that free convection caused by the buoyancy in the heated tube with natural circulation has great influence on the heat transfer characteristics. Based on the experiments, the empirical correlation for the calculation of heat transfer in natural circulation condition has been presented.
