MASS TRANSFER ACCOMPANIED BY INTERRACIAL REACTION DURING DROP FORMATION

抄録

Theoretical analysis of mass transfer accompanied by heterogeneous reaction at the drop surface during drop formation was made for several kinds of reactions.
To interpret the relation between the extent of extraction during drop formation and operational variables such as drop formation time, the concentration of the reactant in both phases and the interfacial reaction rate constant, influences of the interfacial reaction on the overall mass transfer rate were investigated and were expressed by the relation between the reaction factor and the Damköhler number. The reaction factor for the instantaneous mass flux based on penetration theory was approximately expressed by that based on film theory.
It became clear that the extent of extraction is proportional to the drop formation time for a slow interfacial reaction rate but is proportional to the square root of the drop formation time for an instantaneous reaction.
