The two-dimensional viscous froth model for foam rheology and coarsening was analyzed. The model was found to provide a simple and tractable description of the dynamics of a foam by retaining viscous drag forces on the moving Plateau borders. It was suggested that the model can prove a valuable tool for the efficient design of experiments and devices. It was found that the model provides significant insight into strain-rate-dependent effects in foam rheology and elsewhere, particularly in relation to recent experiments.
