This paper covers investigation of nozzle diameter and jet velocity effects on mass transfer coefficient under jetting mode by using experimentation and numerical simulation. For this purpose, a chemical system of n-butanol-succinic acid-water was selected and then vertical liquid jet, containing n-butanol and succinic acid, was injected from nozzles (with inside diameters of 1, 2, and 5 mm) into continuous liquid phase (water) axsimmetrically. The level set method was applied for numerical

... lation of mass transfer between the liquid jet and the continuous liquid. It was revealed that the results obtained from numerical simulation are in good agreement with experimental data and the mean overall mass transfer coefficient for jet mode is on the scale of 10-3 m/s. Also the results of both experimental data and numerical simulation indicate that the overall mass transfer coefficient of the jetting mode is almost one hundred times greater than that of the dropping mode.
