The model includes fragmentation, recoalescence and adsorption of Accepted 13 October 2008 macromolecular emulsifier and uses a simple flow model in order to link the hydrodynamics in the homogenizer to the three physical processes mentioned above. Keywords: A computer model offers an interesting opportunity to study the effect of model assumptions on the High pressure homogenization overall outcome of the process. The computer model is also an interesting complement to experiments in Emulsification this case since internal measurements in the active region of homogenization are very hard to carry out, Recoalescence Fragmentation due to small sca
