为了提高水池内窄缝开口沸腾的临界热流密度（CHF），研究了一种不同模式的相互作用沸腾方法，该方法考虑了核态沸腾和膜态沸腾的不同模式之间的相互作用。采用两种不同热物性的薄材料交替布置在传热板内近表面处（非均匀导热），实现了传热表面的非均匀温度分布。实验进行了两种材料，即聚四氟乙烯和铜的三种不同的宽度和三个间隙尺寸为20 mm 2的传热表面。结果表明，与铜均匀传热板相比，非均匀传热板窄缝处的CHF显著增大。对于宽度为0.5、1.0和2.0 mm的非均匀材料，间隙尺寸为0.54-2.01 mm，CHF增强率分别为34- 43%、47- 68%和26-32%。
To improve the critical heat flux (CHF) of boiling heat transfer in open narrow gaps in a water pool, a method of different-mode-interacting boiling, in which the interactions between the different modes of nucleate and film boiling were expected, was investigated. Two types of thin materials with different thermal properties were alternately arranged inside the heat transfer plate near the surface (nonuniform conductance) was applied to realize the nonuniform temperature distribution on the heat transfer surface. Experiments with three different widths of two materials, namely PTFE and copper and three gap sizes for a 20 mm2heat transfer surface were performed. It was shown that the CHF in the narrow gaps of the heat transfer plate with nonuniform conductance significantly increased compared with the uniform heat transfer plate made of copper. The ratios of CHF enhancement were 34–43%, 47–68%, and 26–32% for width of nonuniform materials of 0.5, 1.0, and 2.0 mm, respectively, with gap size of 0.54–2.01 mm.
