Abstract: | Diffusion accompanied by instantaneous chemical reactions in a multicomponent drop is modeled. The developed model is then
simulated for the case of absorption of one solute from a continuous phase into the drop, followed by fast reactions with
two different reactants existing in the drop. The results of the model are obtained by using Galerkin’s finite element method
and represented by unsteady concentration profiles of all components in the drop, the reaction front positions, and the cumulative
mass flux and the enhancement factor of the diffusing solute. The effects of the system parameters, such as diffusivities
of the solute and the reactants, the relative amount of the reactants in the drop, and the interfacial concentration of the
solute, on the calculated quantities are evaluated. |
