Secondly, for the first time, by volume average concept and reynolds time - average method, a 3d quasi - single phase mass transfer model of distillation tray is deduced by considering the effects of velocity fluctuation, concentration fluctuation and volume fraction of gas and liquid on mass transfer. a source item sc for interphase mass transfer is considered. by applying conventional method of estimating the interphase mass transfer coefficient, a formula for sc is obtained
其次，採用體平均概念、雷諾時均化方法結合塔板氣液相互作用的實際情況首次推導了考慮速度、濃度脈動項和氣、液相含率影響的塔板三維擬單相流湍流傳質模型，源相中考慮了氣液相間傳質項sc ，並運用化工中關于相間傳質系數計算的理論，推導了sc的表達式。 -
3 the degree of solubility depends on the type of gas, its concentration ( more fraction or vapor pressure ), the system pressure, the type of absorbing liquid, and the liquid temperature
溶解程度和氣體種類、濃度、系統壓力、吸收液種類、溫度等多種條件有關。
