CFD modelling of airborne virus diffusion characteristics in a negative pressure room with mixed mode ventilation

COVID-19 caused by severe acute respiratory syndrome (SARS) has accounted for huge collateral damage and as the virus is spreading faster this study deals with isolation rooms or negative pressure 12 more air changes per hour maintaining a difference of 2.5 pa which can help in reducing transmission from affected to not persons. ANSI/ASHRAE/ASHE Standard 170–2008 recommendations are followed hospital applications, facilitate effective ventilation. These prevent spread contaminated particles surroundings creating room whenever door opened atmospheric sucked one present inside room. The Computational fluid dynamics simulations performed investigate diffusion airbone mixed mode ventilation system. It was identified that system controlling droplets
