Foam Evolution in Two Dimensions

摘要

Foams are examples of a large class of systems endowed with a cellular structure pattern: they consist of a tiling of space with comapct polygonal (two dimensions) or polyhedral (three dimensions) domains, separated by what we will consider structureless boundaries [1,2,3,4]. Besides the intrinsic interest in the properties of foamse (e.g. their viscoelasticity), which make them so useful in a large variety of applications [5], foams have been the focus of intensive research within the last two decades, as a paradigm of cellular structure evolution [6,7,8,9].
