A simulation procedure based on Monte-Carlo method was used for simu-lating the processes of drop breakage and coalescence in a vibrating plate tank. Parameters for dispersion dynamics were derived by comparing the results of simulation with experimental data. Drop size distribution and Sauter mean diameter model were also fitted with experimental data. It can be seen that the log-normal distribution could be used to describe the experimental results fairly well. Relationship between Sauter mean diameter and geometrical factors
physical properties of the system and operating conditions has been obtained.
