在６１０ｋＰａ压力条件下，分别对水在垂直上升内螺纹管和光管中的流动沸腾传热进行了实验，并将实验结果进行比较。结果表明，内螺纹管中的流动沸腾换热系数为光管的１６２倍，而且内螺纹管中的起始沸点小于光管中的起始沸点，从流动沸腾传热曲线上可以看到，内螺纹管有提高临界热负荷的趋势。文中对实验结果进行了拟合，提出适用于内螺纹管中流动沸腾换热系数的关联式 Under the pressure of 610kPa, the heat transfer of boiling water flow in vertical rising female screw tube and light pipe was tested. The experimental results were compared. The results show that the flow boiling heat transfer coefficient in the internally threaded tube is 162 times that of the light tube, and the initial boiling point in the internally threaded tube is smaller than the initial boiling point in the tube. As can be seen from the flow boiling heat transfer curve , The female pipe has the tendency of raising critical heat load. In this paper, the experimental results were fitted, and the correlations of flow boiling heat transfer coefficient
