In order to investigate the effects of physical properties on mass transfer coefficiencts, a model starts from the surface renewal theory was described. The model was examined by studing in Lewis cell type for the partially miscible binary and ternary systems.
In the case of partially miscible binary systems, proportionality coefficients calculated from the experimental data showed constant values. An average value of proportionality constant of $1.56\times10^{-3}$ which was estimated from binary systems, was used to evaluate the theoretical mass transfer coefficients for the ternary systems, and compared with experimental results. The experimental values were not good agreement with the theoretical values in this case. It is considered that this deviation is due to the interfacial instability. In the water - cyclohexanone - mixture of cyclohexane and carbon tetrachloride system, the experimental values were good agreement with the theoretical values.
The effect of interfacial tension which was introduced from the concept of Levich - Davies theory was confirmed by the experimental results.
From present experimental results it has to be considered the factors which controlled the degree of interfacial turbulence to analyze the unstable system with interface. The quantitative theory has not been established so far, and further study will be required in this field.
