Based on Higbie's penetration theory and Kolmogoroff's theory of homogenous and isotropic turbulence, the method for calculating the exposure time of liquid particle at the gas-liquid interphase was proposed, and the model for predicting the liquid volumetric mass transfer coefficient was set up. 以Higbie的渗透理论和Kolmogoroff的湍流理论为基础,提出了计算液体表面微元在气液相界面暴露时间的方法,并建立了预测液相体积传质系数的模型方程。
