纯工质池内核沸腾关联式的评价

Evaluation of nuclear pool-boiling heat correlation of pure refrigerant

对池核沸腾换热关联式的研究是一个重要方领域。由于影响沸腾换热的因素比较多,在总结关联式时不能将所有影响因素全部包括。因此现有的关联式的适用范围和精度都还有待于进一步提高。收集了国内外公开发表或现场经常应用的池内沸腾换热系数计算公式。通过对其分析与比较,阐明了公式的适用范围,为准确估算不同工质的池内沸腾换热系数提供了依据。

The heat transfer correlation of nuclear pool - boiling is an important research aspect. Some factors were ignored because too many factors that affected the heat transfer, so the application scope and precision of correlation should be studied farther. The heat transfer coefficient formulas which had been published in home and abroad or usually used in the field were colected, analysed and compared, and the application scope was illustrated.
