Micro-continuum modeling of biofilm growth coupled with hydrodynamics in OpenFOAM

Biofilm growth is a complex phenomenon that couples species transport and reactions with fluid flow dynamics. Simulating these processes in complex geometries remains challenging due to the different time and space scales, as well as the associated computational cost. biofilmFoam is a toolbox based on OpenFOAM that couples advection–diffusion equations with source terms (related to the reactions involved) with the dynamics of the surrounding fluid. This framework provides an efficient basis for performing reliable simulations on any domain or for building more complex models.
