NUMERICAL-ANALYSIS OF MASS-TRANSFER OF A BINARY-SOLUTION DROP WITH DIFFUSIVE SURFACE MASS SUCTION OR INJECTION

Numerical analyses of mass transfer of a binary solution drop with dif fusive surface mass suction or injection were made by use of a finite difference method for Reynolds numbers Re-p = 1 similar to 200, Schmid t numbers Sc-AC = 0.5 similar to 2.0 and Sc-BC = 0.5 similar to 2.0 an d surface mass suction or injection ratios <(phi)over bar> = -0.2 simi lar to 0.2. The diffusion fluxes of a binary solution drop are affecte d by Re-p, SCAC and Sc-BC as well as mass suction or injection ratios, <(phi)over bar>. A new correlation for the effect of diffusive surfac e mass suction or injection on the diffusion fluxes of a binary soluti on drop is proposed in terms of the transfer numbers in ternary system .
