Momentum, with Heat and Mass Transfer through Gas-liquid Interface with Accelerated Interfacial Velocity.

Abstract

Effects of interfacial velocity on interfacial momentum, heat and mass transfer through a gas-liquid interface were quantitatively investigated. The rates of momentum, heat and mass transfer depend not only on the magnitude of the interfacial velocity but also on the change of acceleration in interfacial velocity. In addition, by considering the interfacial tension gradient to be the cause of interfacial acceleration, the effect of the interfacial tension gradient on interfacial velocity, interfacial momentum, heat and mass transfer were also quantitatively investigated. Both the interfacial velocity and the rates of momentum, heat and mass transfer depend not only on the magnitude of the interfacial tension gradient but also on the change of interfacial tension
