Abstract
The relevant mass transport equations have been numerically solved to determine the effect of power-law behavior in the dispersed phase. It is concluded that increased pseudoplasticity in the dispersed phase causes decreases in the total amount of mass transferred, C¯lt, to the droplet because of reduced circulation velocities. Maximum decreases in C¯lt, with increasing pseudoplasticity are realized for larger Peclet number, larger values of the ratio of the viscosity of the dispersed to continuous phase and for smaller Reynolds number. Substantial increases in the total amount of mass transfer are predicted as the regime changes from creeping to that of intermediate Reynolds number flow due to increased contribution of forced convection.
