Abstract
Mass transfer between liquid drops and a surrounding fluid with an accompanying instantaneous chemical reaction is important in a number of industrial processes. For small drops which behave as rigid particles the coupled transport-reaction phenomenon occurs through a moving boundary mechanism. Here we present a theoretical analysis of the problem under non-isothermal conditions by considering the continuous phase diffusional resistance. The relevant transport equations are subjected to a coordinate transformation in order to immobilize the reaction front. Computed results for the enhancement factor and interfacial temperature rise are presented for a wide range of relevant system parameters. The results show enhancement factor and interfacial temperature rise maxima and some other interesting features that can be explained on a physical basis.
