Numerical analysis of indoor aerosol particle deposition and distribution in two-zone ventilation system

A numerical model predicting the air movement and aerosol particle deposition and migration in two interconnected ventilated zones is presented. The airflow patterns and particle distributions in the two-zone ventilated area are presented and analysed. It is concluded that particle deposition and migration are mainly influenced by the particle properties, the ventilation conditions and the airflow patterns in the two zones. Small particles have a greater potential for inhalation by building occupants than do larger particles.
