The effect of interfacial velocity and interfacial tension gradient on momentum, heat and mass transfer through fluid-liquid interfaces was studied numerically. The effect of interfacial tension gradient on the interfacial velocity was clarified. The results obtained in this study can explain quantitatively the previous experimental results on the interfacial acceleration due to the interfacial tension gradient. Interfacial contamination and interfacial turbulent phenomena were respectively related to the enhancement and suppression of the mobility of interface. Effects of physical properties, bulk flow speed and Prandtl number on starting points of interfacial turbulence were also discussed.
