A simulation model has been developed to model the drop size distribution of a homogeneous dispersion sustained by turbulent agitation. From a fundamental point of view, the four drop rate processes of drop coalescence, drop breakage, drop movement into, and drop movement out of a control volume were recognized. This simulation algorithm deals with the interactions of the four drop rate processes by following representative drops and using Monte Carlo techniques to simulate the processes. Thus, the shortcomings of previous simulation techniques have been eliminated. Compatibility of this simulation model with the population balance equation is also illustrated. The model is corroborated with experimental data of drop size probability and coalescence frequencies. This simulation model has the potential to model more complicated systems with further modification, and may then be used as a scale-up tool.
