Numerical investigation on the influence of contaminant source location, occupant distribution and air distribution on emergency ventilation strategy

A new concept, called Integrated Accessibility of Contaminant Source (IACS), has been proposed to consider simultaneously the positioning of a contaminant source, the distribution of occupants along with the overall airflow pattern. 84 cases with different combinations of contaminant sources and ventilation style in a full-scale room have been investigated numerically for that study. From the results obtained, some rules are proposed to advise the best ventilation strategies for different situations.
