摘要
以水为工质 ,对套管式换热元件进行了单相对流传热强化效果和传热性能的实验研究 .根据实验结果 ,给出了窄环隙流道单相对流传热时内、外侧的努谢尔特数与雷诺数的关系 .实验结果分析表明 ,在雷诺数Re <2 0 0 0时 ,窄环隙流道依然具有强化传热特点 .
Experiments were conducted to investigate the enhanced effect and heat transfer performance of water through the narrow annular channel.According to the experimental results,the correlations between the inner face and outer face Nusselt number and Reynolds number were given.The experimental results showed that the narrow annular channel manifested itself in the effect of enhanced heat transfer in the region of Re<2000.
