Trimodal dispersions

Drop sizes depend on many factors that are discussed throughout this chapter. For any given system, drop sizes are never uniform rather, they exist in a continuous size spectrum. The large end of the drop size spectrum is controlled by agitation intensity, and the small end by the physics of drop breakage events. The DSD is sometimes bimodal or trimodal. Multimodal distributions are usually a result of multiple breakage mechanisms and unusual breakage patterns, such as those that result when viscous and/or viscoelastic drops are dispersed. Certain coalescence events can also lead to bimodal drop size distributions.
