Dynamics and dissipation in 2D fluid foams: The foamy continuum model

The paper establishes the governing equations of the dynamics of a foamy continuum , in the sense of Davini and Podio-Guidugli, which is expected to mimic the behavior of a monodisperse fluid foam. We model this special continuum as a dissipative ordered fluid, following the lead by Sonnet and Virga. Attention to both regular and topological transformations is taken.
