Mass transfer at the confining wall of a coiled flow inverter

Abstract

An experimental investigation on liquid-wall mass transfer at the internal wall of a coiled flow inverter is carried out. Computation of the mass transfer coefficient is made from measured limiting currents at point electrodes fixed flush with the inner surface of the coiled flow inverter. Variation of mass transfer coefficient with respect to liquid velocity is studied. The coiled flow inverter yielded an enhancement of 125% in mass transfer coefficient against the reported enhancement of 35% in heat transfer. The data were correlated using the least squares regression method and a correlation equation is obtained.
