摘要：选用几种液液体系，研究了浓度推动力引发的界面扰动对传质速率的增强效应．实验在扩散槽中进行，利用激光全息干涉装置拍摄了界面现象的全息图．结果表明，由于界面扰动，传质总系数可增大１．５～４倍．
The enhancement of the rate of mass transfer due to concentration driving force induced interfacial turbulence has been investigated in several typical liquid liquid systems.The experiments were carried out in a diffusional cell and the holograms of interfacial phenomena were taken by using a laser interferometry system.The results showed that the over all mass transfer coefficients increased about 1.5～4 times for the interfacial turbulence. The correlation for predicting mass transfer coefficient was obtained.
