| 摘 要： | 根据环形管内流动与传热的特点,重新定义了环形管的水力直径和热周直径,基于圆管环状流CHF解析模型,得到了环形管内环状流临界热负荷解析模型。该模型可以预测环形管内沸腾两相流环状流时在不同加热方式下发生的临界热负荷,加热方式包括有内侧加热、外侧加热、两侧同时加热等。数值预测结果与文献数据比较表明本文的解析模型在P=0.57-15.01.MPa,G=198-3789.5 kgm-2s-1,xc=0.068-0.855,L/Dhe=19.3-539.5范围内预测良好。

| Abstract: | Both hydraulic diameter and thermal diameter are re-defined according to the flow dynamic and heat transfer characteristic in annulus tube. And then, a physical model of critical heat flux used to circular tube is developed to predict the critical heat flux in annulus tubes. The physical model can be used to calculate the critical heat flux for boiling annular flow with different heating conditions, which are unilateral inner wall or outer wall heating, and dual tube walls heating. The prediction results agrees well with the referenced data, which shows that the physical model can be used in the following parameters ranges: P = 0.57 - 15.01 MPa , G = 198 - 3789.5 kgm-2s-1 , xc = 0.068-0.855 , L/Dhe= 19.3-539.5. |
