Mass transfer in liquid‐liquid dispersions in a turbulent flow field has been investigated for the particular case where the overall process rate is governed by the diffusional resistance in the dispersed phase. Experiments with the system water‐iodine‐carbon tetrachloride have shown that the transfer mechanism in this case is similar to that for single drops at high Reynolds numbers. The results obtained show that the so‐called correlation factor R depends strongly on the turbulence of the system. This relationship can be expressed as R ˜ R 2 , which is valid for the mass transfer rate both in turbulent liquid‐liquid dispersions and for some cases of solute diffusion in single oscillating drops.
