Contribution to the modelization of the emulsification in a colloid mill

Abstract

We propose a stochastic model to forecast the droplet size distributions of oil in water emulsions generated in a colloid mill. The model lays on breakup sequences of the oil droplets induced by the shear field existing within the mill. One single set of the three fitting parameters is sufficient to account for the variations of the droplet size distributions in function of the surfactant concentration, the surfacant nature, the rotation speed of the rotor.
