Similarities between the effect of different flow patterns on diffusion with chemical reaction near an interface

Abstract

Theoretical models of mass transfer across an interface generally ignore the effect of velocity variation. For mass transfer accompanied by psuedo nth order reaction, it is shown that, at sufficiently high values of reaction rate constant, the rate of mass transfer will be independent of the velocity variation. Thus, in scale-up studies, it is often unnecessary to match flow conditions in laboratory and large-scale equipment, so that laboratory apparatus may safely be chosen on the grounds of simplicity and convenience.
