Two mechanical models——recirculating flow and sliding bubbles, which lead to the bundle effect in nucleate boiling on tube bundle are established and calculated quantitatively. The correlation of nucleate boiling on tube bundle is put forward on the basis of experiments, and the influence on boiling heat transfer is analysed.

对管束核态沸腾引起管束效应的对流循环和滑移汽泡两种机制作了模型假设和定量计算。并在实验基础上拟合了管束核态沸腾平均换热系数计算公式,分析了两种机制对换热的影响。

An experimental investigation of pool boiling heat transfer is carried out in a horizontal tube bundle with 8 rows and 3 columns of tubes, and a pitch - to - diameter ratio of 1. 667. The working fluid is R-113. Heat transfer coefficients are measured for each row of tube, and it is found that the heat transfer coefficient increases for higher heat flux and higher position in the tube bundle. The measurements show that there exists a large bundle effect. In addition, boiling curve...

An experimental investigation of pool boiling heat transfer is carried out in a horizontal tube bundle with 8 rows and 3 columns of tubes, and a pitch - to - diameter ratio of 1. 667. The working fluid is R-113. Heat transfer coefficients are measured for each row of tube, and it is found that the heat transfer coefficient increases for higher heat flux and higher position in the tube bundle. The measurements show that there exists a large bundle effect. In addition, boiling curve hysteresis in tube bundle is found. The correlations of boiling heat transfer coefficients are obtained.

通过对氟里昂R-113在水平管束管外地沸腾的实验研究,分析了管束沸腾的滞后现象及沸腾换热系数的管束效应.得出了管束沸腾换热系数的经验关系式,并讨论了关系式中系数和指数与换热机理的内在联系.

A separated model is developed for the recirculating flow and heat transfer in a kettle reboiler tube bundle. Subcooled boiling at the bottom of the bundle and some recirculating liquid entering the bundle from its sides are considered. Compared with previous models, this model has more reasonable agreement with the experimental results by Cornwell et al. The effects of heat flux, liquid level and subcooled boiling length on the recirculating flow rate and heat transfer coefficient are examined....

A separated model is developed for the recirculating flow and heat transfer in a kettle reboiler tube bundle. Subcooled boiling at the bottom of the bundle and some recirculating liquid entering the bundle from its sides are considered. Compared with previous models, this model has more reasonable agreement with the experimental results by Cornwell et al. The effects of heat flux, liquid level and subcooled boiling length on the recirculating flow rate and heat transfer coefficient are examined. The height of subcooled fraction of the tube bundle decreases with increasing heat flux. Therefore, the effect of subcooled boiling is outstanding at low and middle heat flux. Owing to the existence of side flow,the recirculating flow rate increases for higher tube rows in the subcooled boiling region, and maintains constant in the saturated boiling region.

提出了釜式再沸器管束中循环流动换热的分相预报新模型,考虑了管束下部的过冷沸腾及循环液体的侧面引入。与以往的模型相比,本文模型与现有实验数据符合更好。
