Abstract

Abstract:

Bacteria biofilms are widespread in nature and industrial environments. A bacteria biofilm is regarded as an incompressible viscous fluid composed of multiplecomponents. The theory of multiple-phase field, material continuity equation, momentum conservation equation, field control equations and biological reaction dynamic equation are combined to model bacterial biofilm growth dynamics. A numerical solution of the multiplecomponent bacterial biofilm growth dynamical model is used to describe the growth of bacteria, the law of nutriment’s consumption, and extracellular polymers in static and dynamic environments.

Key words: dynamical model, numerical simulation, phase field theory, bacteria biofilm
