The combined effect of free and forced convections on mass transfer between two liquids was studied experimentally and theoretically. In the experiments, steady-state dissolution rates into flowing water of an aniline or furfural drop which was sandwiched between a capillary and a rod and had a nearly cylindrical surface were measured, and the continuous-phase mass transfer coefficients were obtained. During an experimental run, the amount of the drop phase dissolved into water was supplied continuously through the capillary and the drop volume was kept constant. It was observed that the Sh values depend on the flow direction of water in the range of 5<Re< 100 and that in the case of upward flow, Sh takes the minimum at some Re number. Numerical simulations of the phenomena were tried, using the finite element method, and the experimental results are explained qualitatively.
