Comparison of experimental results and numerical predictions of drop diameter from a single submerged nozzle in a liquid-liquid system

This paper presents a comparison of experimental results and numerical pred ictions of drop formation from a single submerged nozzle for a liquid-liqui d system. The theoretical model is a modification of previous models used f or a two-stage drop formation mechanism. The model has been tested against experimental data for kerosene drop formation in distilled water using a ra nge of different nozzle diameters. In addition, our liquid-liquid model has been compared with both experimental and predicted results from published literature. These comparisons demonstrate that for liquid-liquid systems, t he present predictions of drop diameter versus dispersed phase nozzle veloc ity are in overall agreement with both the present and previous experimenta l results. In addition, the present model predictions are more accurate tha n those of previous models for liquid-liquid systems.
