摘要
本文对饱和池沸腾状态下的临界热流 (CHF)模型及其新发展进行了归纳和总结。经研究分析发现 ,现有实验结果的解释理论还不够充分 ,其中的分析模型都是基于时间平均和空间平均后的结果 ,掩盖了沸腾的动态特性。因此要引入新的实验手段来研究各影响参数对CHF的作用。提出了要利用微型光学探头和微型热电偶来对厚液层的流体性质和热工性质进行实验研究 ,以获得对CHF现象更深入的认识。
This article has a review of the models and the new developments of the saturated critical heat flux (CHF) of the pool boiling.After literature analyzing,notes that the analysis to the available experimental facts is not enough yet .Almost all the theoretical models is deduced by time-averaged or space-averaged methods ,which could cover up the dynamic characteristic of boiling.So we need the new experimental methods,such as micro-optical probe,micro-thermocouple etc,to investigate the roles of those influential parameters in CHF.
