Modelling and measurement of airflow and aerosol particle distribution in a ventilated two-zone chamber

A CFD analysis of air movement and aerosol particle deposition and distribution in a ventilated two-zone system with a small interzonal opening is presented. The comparisons of average particle concentrations in both zones between computations and experiments are generally satisfactory and acceptable. 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 influence on the indoor air quality than do the large particles.
