Study on Heat Transfer Correlation in Supercritical Water through a Vertical Tube
-
摘要: 基于圆管内超临界水传热试验数据建立传热系数的预测关联式。将本文关联式和相关文献关联式预测结果与试验数据进行对比,全面比较各关联式的适用性和通用性。结果表明:本文建立的关联式具有较宽的预测范围,不仅可以预测超临界水正常传热,还可以预测传热强化和传热恶化等典型传热行为。Abstract: A semi-empirical heat transfer correlation is investigated based on the heat transfer experimental data.Calculations predicted by using literature and present correlations are evaluated and compared with the present experiments and literature experiments.Results show that the present correlation can well predict the heat transfer enhancement and heat transfer deterioration phenomenon,rather than the normal heat transfer of the supercritical water.
