【摘要】 本文对池沸腾随液位下降到某一特定值后,沸腾传热会出现恶化的现象进行了研究,通过建立物理模型和理论分析,导出了低液位沸腾转化点液位的数学表达式。在大气压力下,用蒸馏水和乙醇做实验对理论进行了验证。理论值与其它学者的实验值及本文的实验值都吻合得很好。更多还原

【Abstract】 The present paper researches phenomenon that boiling heat transfer will become bad when the boiling liquid level decreases below some level. According to a physical model of the phenomenon proposed by authors,a expression of the liquid level at the transforming point has been deduced by theoretical analysis.The comparison is made between the the theoreti- cal values and the experimental results done with distilled water and ethyl alcohol at atmospheric pressure.The theoretical values agree well with the experimental results of authors and other observers.更多还原
