Abstract
A system of two immiscible liquids agitated in a batch reactor under the action of impellers gives rise to a set of droplets of one phase dispersed in the other phase. The resulting system is called a dispersion (finer dispersions are called emulsions) and its evolution is caused by the fact that droplets during their motion may break up in two or more smaller droplets or they may coalesce (an essentially binary process), producing larger elements. Dispersions are commonly encountered food industry, cosmetics, pharmacology, photography and many others industrial processes. This justifies the large amount of scientific papers devoted to this subject during the last century (see, for example, References [1–3] for the main relevant literature). However, many basic questions are still pending so that research is still very active in this area (see, for example, References [4–9]).File | Dimensione | Formato | |
