Abstract It is now well known that the control of airflow pattern in hospital can mitigate the spread of infectious diseases such as measles, tuberculosis and severe acute respiratory syndrome (SARS). There are guidelines to control aerosol dispersion in isolation rooms by the U.S. Centers for Disease Control and Prevention (CDC), in which specific ventilation systems recommended for different circumstances. However, there is still lack of guidelines for public buildings. The person-to-person contaminant transport in public spaces is quite complicated, and is affected by the ventilation airflow, thermal plume around human bodies, human respiration and/or other activities. In addition, earlier studies were focused on limited particle sizes and environmental conditions. In this study, detailed analyses of person-to-person aerosol transport in public spaces with various ventilation systems are performed. An Eulerian-Lagrangian approach were used computational fluid and particle simulation in ventilated room with realistic manikins. The study provided improved understanding of person-to-person contaminant transport.
