【摘要】：细菌生物膜普遍存在于自然界和工业环境中.将细菌生物膜视为由多种组元组成的不可压缩的黏性流体,结合多元相场理论、物质连续方程、动量守恒方程、溶质场控制方程和生物反应动力方程对细菌生物膜生长动力学进行建模.通过对模型的数值模拟,可以描述细菌和胞外聚合物在静态环境和动态环境中的生长状况以及营养物质的消耗规律.
[Abstract]:Bacterial biofilms are ubiquitous in natural and industrial environments. The bacterial biofilm is regarded as an incompressible viscous fluid composed of many components, combined with the theory of multicomponent phase field, the equation of material continuity, the equation of conservation of momentum, The dynamics of bacterial biofilm growth was modeled by solute field governing equation and bioreactor dynamic equation. Through the numerical simulation of the model, the growth of bacteria and extracellular polymers in static and dynamic environment and the rule of nutrient consumption can be described.
