Abstract

The discussion initiated by a brief message by Prof. E.D. Fedorovich allows for briefly recalling the evolution of ideas about the nature of the boiling crisis. Although the hydrodynamic model of the crisis, due to its clarity and simplicity of the calculation formula that follows from it, remains the most popular among specialists, experiments of the last 10–15 years confirm that this model objectively has no relation to nucleate boiling of a liquid. In most modern studies, an irreversible increase in the area of dry spots on the heating surface is taken as the cause of the crisis. A quantitative model based on this hypothesis was proposed by the author in 1988. However, in the absence of a rigorous mathematical description of the nucleate boiling process, any model in this area is approximate and long life is guaranteed for discussions about the mechanisms of the boiling crisis.

关于沸腾危机的机制（ED Fedorovich的文章“关于开发加热润湿表面的液体沸腾危机的两阶段模型的权宜之计”）

摘要

ED Fedorovich教授的简短信息引发的讨论使我们可以简短地回顾一下沸腾危机的性质的思想演变。尽管危机的水动力模型由于其简洁明了的计算公式而仍然是最受专家欢迎的模型，但最近10到15年的实验证实，该模型客观上与核的沸腾无关。液体。在大多数现代研究中，加热表面干燥点面积的不可逆转增长被认为是造成危机的原因。作者于1988年提出了基于该假设的定量模型。但是，由于缺乏对核沸腾过程的严格数学描述，
