Phys. Rev. E 70, 041411 (2004) [13 pages]Two-dimensional viscous froth model for foam dynamicsReceived 1 December 2003; revised 1 June 2004; published 29 October 2004 The two-dimensional viscous froth model is a simple tractable model for foam rheology and coarsening. It includes, but is not confined to, the quasistatic regime. Here we present a detailed analysis and implementation of the model, illustrated with various examples. With certain simplifying assumptions, it provides significant insight into strain-rate-dependent effects in foam rheology and elsewhere, particularly in relation to recent experiments. © 2004 The American Physical Society URL:
