(Biocomplexity Institute, Department of Physics, Indiana University)
The Cellular Potts model has been succesfully used to model foam drainage as well as stress and strain in sheared foams. Here we investigate instabilities due to the flow of a single large bubble in a monodisperse flowing foam using the Cellular Potts model. As expected, above a certain threshold velocity, the large bubble moves faster than the mean flow. Our simulations reproduce recent experimental results of foam flow in a Hele-Shaw cell and reflect the importance of the cellular Potts model in successfully studying foam rheology.
