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。
In this paper, a dynamic physical model of liquid film boiling critical level is proposed, and then the mathematical expression of the liquid level is obtained by theoretical analysis and mathematical derivation. Under atmospheric pressure, the theoretical expression was verified by experiments with distilled water and ethanol. The theoretical value is basically consistent with the experimental value of the scholars in various countries and the experimental value of this paper. At the same time, with the help of high-speed photography, the dynamic physical model of critical level was verified. The photos obtained show that the model does exist.
