Interfacial Turbulence in Gas-Liquid Mass Transfer

Abstract

Fundamental characteristics of interfacial turbulence in gas-liquid mass transfer were studied by desorbing six surface tension-lowering solutes from aqueous solution in a liquid jet column and a wetted wall column, and monitoring the liquid-phase mass transfer coefficient by simultaneous transfer of oxygen as a tracer component. A general correlation of the enhancement factor R vs. the Marangoni number is obtained as R=(Ma/Mac)n. Where n is revealed to have a constant value of 0.4±0.1. A diagram is proposed to estimate the critical Marangoni number Mac. © 1980, The Society of Chemical Engineers, Japan. All rights reserved.
