The critical heat flux (CHF) of subcooled boiling is theoretically predicted by using the microlayer model.

本文利用微液层模型对过冷沸腾的流密度（CHF）进行了理论预测。

Experimental study was performed using water as working medium to investigate the flow instability in a vertical narrow annuli with both subcooled and saturated boilings.

以水为工,分别在过冷和饱和条件下对竖直流道进行了自然对流沸腾流动不稳定性实验,观测到了流道饱和沸腾时所特有的蒸干型流动不稳定性。
