摘要 本文对二维窄缝形喷嘴垂直喷流高速冲击冷却滞止区受热平板的饱和液体喷流沸腾临界热流密度(CHF)进行了实验研究,通过理论推导和实验数据的归纳处理.得到了一个无量纲半理论半经验型预示公式.同时也对高速过冷液体喷流沸腾CHF进行了实验研究.并推导出预示公式.对高速喷流时喷流速度和过冷度影响滞止区喷流沸腾CHF的机理进行了定量解释.对高速喷流条件下喷流速度和过冷度对滞止区高速喷流沸腾CHF的影响进行了深入讨论,从理论分析和实验验证两方面探讨了饱和或过冷液体二维喷流沸腾时CHF达到最大值所对应的最大喷流速度,以及所对应的CHF的极限值. A non-dimensional semi-theoretical and semi-empirical correlation for predicting the critical heat flux (CHF) of steady boiling for high velocity saturated water vertical slot jet impinging on the stagnation zone was proposed and the correlation factor was determined from the experimental data induction. Meanwhile, a prediction correlation on the CHF of steady boiling for subcooled water jet impinging on the stagnation zone was also obtained from an experimental investigation. The mechanism of the impact velocity and subcooling effect on the CHF of steady boiling for jet impinging on the stagnation zone was quantitatively explained. The effect of high impact velocity on the CHF of steady boiling for jet impinging on the stagnation zone was further discussed and two kinds of effects were under observation.
