THE MODELING OF LIQUID AND SOLID FOAMS

The study of foams, both liquid and solid, has led to a deeper underst anding of many of the aspects associated with cellular systems in gene ral. The 2-dimensional liquid foam is fully examined and a computation al model for this system, which has been tested extensively, is outlin ed. Recent observations of 3-dimensional liquid foams are presented, t hese suggesting a revision of the prevailing view that monodisperse fo ams are generally disordered. Suggestions for further work, computatio nal and experimental, are given. A newly developed model for 2-dimensi onal solid foams is outlined, including the relationships that are nec essary when discretizing the energy equations associated with a contin uous system.
