Covid 19-related research

Research is ongoing on the mixing and ventilation of aerosols and viruses in buildings. Key results and publications will be added below as they become available.

• The ventilation of buildings and other mitigating measures for COVID-19: a focus on wintertime (Proc. R. Soc. A. 477), where we review knowledge of the transmission of COVID-19 indoors, examine the evidence for mitigating measures, and consider the implications for wintertime with a focus on ventilation.
• The impact of hospital ward ventilation on airborne pathogen exposure (Am. J. Respir. Crit. Care Med., 203(6)), where we present the results of a monitoring campaign in the cystic fibrosis ward in the new Royal Papworth Hospital in Cambridge.
• The mixing of airborne contaminants by the repeated passage of people along a corridor (J. Fluid Mech. 903), where we show that people walking through a space drive significant mixing of the air, causing viruses and aerosols to be transported long distances and remain suspended in the air for a long time.
• Analogue Laboratory Modelling of Ventilation in Nightingale Hospitals, where we compare different strategies for the ventilation of a ward.
• Coronavirus Pandemic: Making Safer Emergency Hospitals. Healthcare authorities are attempting to add thousands of additional bed spaces by temporarily adapting any available large open halls. Here, we compare different low-tech adaptations to ventilation systems and ward configuration.
• On the transport of heavy particles through an upward displacement ventilated space (J. Fluid Mech. 772), where we investigate the removal of contaminants from a warm room using displacement ventilation.
• On the transport of heavy particles through a downward displacement ventilated space (J. Fluid Mech. 774), where we investigate the removal of contaminants from a room containing a source of cooling.
