Coalescence and breakage processes

Abstract We extend a model for coalescence and breakage of liquid–liquid dispersions proposed by Fasano/Rosso. The main feature is that the experimentally observed fact of a maximal droplet mass is taken into account. Our model includes spontaneous breakage as well as collisional fragmentation. Existence and uniqueness of solutions is proved and the long‐time behaviour is investigated. Copyright © 2002 John Wiley & Sons, Ltd.
