摘要
在1.0～4.5MPa的压力范围内研究了1.2mm间隙环形窄缝通道内过冷沸腾起始点。分析了部分热工参量对沸腾起始点的影响。引入双面加热影响因子,对环形窄缝内过冷沸腾起始点的数据进行回归分析,得出了适用于环形窄缝过冷沸腾起始点的实验关系式。
The onset of nucleate boiling (ONB) was investigated for water flowing in the annular duct which clearance is 1.2 mm at the pressure range from 1.0 to 4.5 MPa. The effect on ONB of some thermodynamics parameters was also analyzed. The available data dealing with sub-cooled boiling initial point of water in narrow annular clearance duct are analyzed by using regression method. The new developed correlation was obtained by considering the bilateral heating factor.
