New Mathematical Model for True Boiling Point Distillation and ASTM Distillation Curve of Petroleum Fractions 石油馏分实沸点蒸馏曲线与恩氏蒸馏曲线关系的新数学模型
The boiling curve hysteresis phenomena from thin particle porous layers in a vacum state are experimentally researched, using Ethyl alcohol as test liquid. 以乙醇为工质,实验探索了颗粒多孔层在真空状态下的沸腾滞后现象,以及系统真空度、液体过冷度和多孔层结构参数对它的影响。
The active nucleation densities of different material surfaces are predicted using the heat transfer model and the data of the nucleate boiling of different cryogenic liquids. The active nucleation site density curve is agreed well with the fractal model of active sites density proposed by the author. 运用核沸腾换热机理模型和不同低温液体的沸腾换热数据预测了不同热物性表面的活化核心密度,预测得到的活化核心密度曲线与作者提出的沸腾表面活化核。
