Numerical simulation of two-dimensional soap froth

The temporal evolution of two-dimensional foam is studied by event-driven numerical simulations based on different types of models. It is shown that most of the dynamical and topological features seen in experimental measurements can be reproduced. The average area of cells scales linearly with time and the distribution of n-sided cells can be compared with known results. The topological models regarding the lengths of the boundaries yield the best results among the models studied.
