临界热流密度流体模化研究进展

Research progress on fluid-to-fluid modeling method of critical heat flux in flow and boiling heat transfer

探讨了模化工质的选择原则,总结比较了目前比较成功的四种预测模型,并从研究较多的流道形式出发,总结了各流道形式的研究现状,发现当下的预测模型适用不同流道形式和相同流道不同工况时,模化效果不理想。最后提出采用流体模化方法研究微通道流动沸腾CHF的必要性。

The selection principle of modeling fluid was discussed, and four modeling methods which were successful at present were analyzed and compared. The research status of all sorts of channel types were summarized based on those channel types studied a lot. It was found that the modeling effect was not always suitable when the current prediction models were applied to different channel types or the same channel type in different working conditions. At last, the ne- cessity of applying fluid-to-fluid modeling method to the study of the critical heat flux （CHF） of flow boiling was expounded.
