マルチスケール計算化学に基づく汚れ付着シミュレーション技術の開発

抄録

Plumbing stains grow up from invisible attachment of urea and urolith in the molecular level to biofilms in which bacteria adsorb such nutrients and secrete extracellular polymer substances. In order to understand and control such biofilm growth, we have developed a multiscale simulation that can analyze from adhesion of stains on the molecular scale to accumulation of biofilm on actual scale. In the present study, the biofilm growth and peeling by shear flow was successfully simulated for the condition of typical toilet use.
