Abstract
This short report substantiates the advisability of developing a two-stage model for the emergence and development of a boiling crisis. One of the stages is the violation of the stability of the two-phase wall layer, and the other is the appearance and fusion of dry spots on the heating surface. The use of a two-stage (“temporary”) model makes it possible to combine both well-known approaches to crisis analysis—hydrodynamic and thermal—in a single logical system. In the first approach, the characteristics of the boiling crisis are characteristic of high pressures in a boiling liquid, while those in the second are for low pressures.

液体润湿受热面沸腾危机两阶段模型的权宜之计
摘要
这份简短的报告证实了为沸腾危机的发生和发展建立两阶段模型的明智性。一个阶段是破坏两相壁层的稳定性,另一个阶段是加热表面上干燥点的出现和融合。通过使用两阶段(“临时”)模型,可以在单个逻辑系统中将两种众所周知的危机分析方法(流体动力和热力分析)结合起来。在第一种方法中,沸腾危机的特征是沸腾液体中的高压特征,而在第二种方法中,则是低压。
