Airflow patterns around two people conversing in typical situations, such as hair salons, medical exam rooms, and long-term care facilities. COVID-19 can spread from asymptomatic…
More preventive measures, such as shielding underneath tables and improving air conditioner filtration efficiency, could reduce exposure to COVID-19 within air-conditioned restaurants. The detailed physical…
Editor’s note: Varghese Mathai is a physicist at the University of Massachusetts Amherst who studies the flow of fluids and gases. He conducted a study…
A computation shows air purifiers in elevators and other confined spaces can actually increase saliva droplet dispersal, spreading COVID-19. The positions of air inlets and…
Engineers make it possible to simulate complete ‘dance’ of colliding vortices at reduced computational time. In 2018, passengers onboard a flight to Australia experienced a…
An open-faced helmet connected to an air filtration pump decreases risk of disease transmission from patients to dentists or otolaryngologists. The risk of infection of…
Researchers from the National Graphene Institute at the University of Manchester and the University of Pennsylvania identify ultra-fast gas flows through atomic-scale apertures in 2D…
A portable device can determine aerosol concentrations in public spaces. Because of the role they play in coronavirus transmission, understanding aerosol concentrations and persistence in…
On a clear day, the towering peaks on Fogo, Santa Antão, and São Nicolau stand out amid the flatter islands of Cabo Verde (Cape Verde)….
A computer model deepens our understanding of airflow while wearing face masks, where particles land in the respiratory tract and the effectiveness of three-layer surgical…
Simply wearing a mask may not be enough to prevent the spread of COVID-19 without social distancing. In Physics of Fluids, by AIP Publishing, researchers tested…
Fast walking in narrow corridors can increase COVID-19 transmission risk. Long streams of virus-laden droplets can trail behind infected individuals walking through a narrow corridor,…
Understanding Dangerous Droplet Dynamics New fluid dynamics research reveals why social distancing alone doesn’t necessarily prevent infection indoors and how to detect COVID-19 super-spreaders. Researchers…
Face masks slow spread of COVID-19; types of masks, length of use matter. The use of face masks to help slow the spread of COVID-19…
Sneezes from people who have congested noses and a full set of teeth travel about 60% farther than from people who don’t, according to a…
The Contagion Airborne Transmission inequality model illustrates correlation between physical distancing and protection, the efficacy of face masks and the impact of physical activity on…
In specially coated tubes, the more viscous a liquid is, the faster it flows. It’s widely known that thick, viscous liquids — like honey —…
Discovery of a topological change of an interfacial hydrodynamics by a partial miscibility and creating a cross-disciplinary discipline of chemical thermodynamics and interfacial hydrodynamics. The…
