Effect of airborne pathogen transmission released by an assailant in a mosque using CFD simulation.

This study investigated the aerosol particle spreading characteristic under transient state at different location released by an assailant inside a mosque. Particles deposited at receivers were used to determine the virus reproductive number (Ro) over time. The spreading during coughing process was...
