摘要
针对工业领域中常见的低温工质自然对流传热现象,该文研发了一套用于水平环缝内低温工质自然对流传热实验的装置,介绍了实验装置的结构和原理,并进行了初步的性能测试。结果表明,利用该装置测得的实验数据精度较高,能够满足相关实验要求。该装置可同时用于水平同心和偏心环缝内低温工质自然对流传热实验研究。
For the phenomenon of natural convection with low-temperature fluids in industrial field,an experimental device of natural convection heat transfer with low-temperature fluids used in horizontal annulus is developed.The structure and principle of this experimental device are introduced and the primary experimental performance is tested.Results show that the precision of the experimental data is high and it can meet the requirements of the relevant experiments.The device can be used in the research of natural convection heat transfer with low-temperature fluids both in the horizontal concentric and eccentric annulus.
