【摘要】 本文提出了关于液膜沸腾临界液位的动态物理模型,进而由理论分析和数学推导,求得了该液位的数学表达式。在大气压下,用蒸馏水及乙醇做实验对理论表达式进行了验证。理论值与各国学者的实验值及本文的实验值基本上吻合。同时借助于高速摄影对临界液位的动态物理模型进行了可视性检验。得到的照片证明了该模型的确存在。更多还原

【Abstract】 This paper presents a dynamic physical model about the critical liquid Level of boiling in Liquid film.By theoretical analysis and mathematical deducing,a expression of the critical Liquid Level is obtained.The com parison is made between the theoretical values and the experimental results done with distilled water and ethyl alcohol at atmospheric pressure.The theoretical values agree well with the experimental values of authors and other observers.A visible test of the dynamic model is carried out by means of high-speed phtography.The obtained pictures show that the dynamic model is true.更多还原
