Abstract
Air flow inside a large lecture hall is simulated using CFD. The predicted flow field is used to estimate the residence time for any pathogen released from specific locations inside the domain. The approach developed herein is generic, and can be used for the assessment of any large confined spaces like lecture halls, theatres, cinema halls etc.for the spread of air-borne diseases.
