Abstract
The mass transfer enhancement of a two-phase flow system containing reactive dispersed droplets has been studied on a vertical planar electrode. A static mixer was used to generate organic droplets dispersed in the continuous aqueous solution.
The limiting current method was used for the mass transfer rate measurement. A mass transfer mechanism model was proposed to describe the mass transfer phenomena of the two-phase flow system. Experimental strategies were developed to separate the measured total limiting current density into three individual mass transfer mechanisms--namely, the one-phase convective flow mechanism, the disturbance mechanism, and the wetting mechanism.
The important two-phase flow operating variables that were investigated include the dispersed phase volume fraction, the dispersed droplet size, the two-phase flow velocity, the electrode material, and the turbulent promoter.
The results of this study could be applied to battery energy storage systems and electro-organic synthesis processes.
