Abstract: A model of mass transfer coefficients in liquid phase near free gas-liquid interface is developed based on the energy spectrum functions of isotropic turbulence.The calculated results for the mass transfer coefficients in pipe flows and stirrer tanks agree well with the measured data reported in articles.

摘要: 在单涡模型的基础上 ,根据各向同性湍流的能谱函数 ,考虑不同尺度的旋涡对气液传质的影响 ,建立了气液自由界面传质系数模型 .模型计算结果与管道流及搅拌反应釜的实验结果吻合较好.
