Numerical modeling of the mechanical response of bacterial biofilm to flow by using an SPH poroviscoelastic model

Abstract

We present a weakly-compressible two-phase poroviscoelastic biofilm model based on Smoothed Particle Hydrodynamics (SPH) method. The biofilm is modeled as a mixture of solid and fluid phases interacting via drag forces. Benefiting from the Lagrangian feature of the SPH method, large deformations of the solid structure can be modeled straightforwardly.
