An extended mathematical mesoscale model for flow effects in a biofilm is developed, allowing flow through the EPS matrix and through microchannels that could not be explicitly resolved in previous mesoscopic simulation studies. The model consists of the usual Navier–Stokes equations in the bulk liquid and a porous medium model in the biofilm itself. The sensitivity with respect to the new model parameter is studied numerically by computer simulations.
