Flow physics plays a key role in nearly every facet of the COVID-19 pandemic. This includes the generation and aerosolization of virus-laden respiratory droplets from a host, its airborne dispersion and deposition on surfaces, as well as the subsequent inhalation of these bioaerosols by unsuspecting recipients. Fluid dynamics is also key to preventative measures such as the use of face masks, hand washing, ventilation of indoor environments and even social distancing. This article summarizes what we know and, more importantly, what we need to learn about the science underlying these issues so that we are better prepared to tackle the next outbreak of COVID-19 or a similar disease.read more

TL;DR: In this article, the authors discuss current evidence regarding the transmission of respiratory viruses by aerosols-how they are generated, transported, and deposited, as well as the factors affecting the relative contributions of droplet-spray deposition versus aerosol inhalation as modes of transmission.

Effects of ventilation on the indoor spread of COVID-19
TL;DR: The role of building ventilation on the possible pathways of airborne particles and the fluid mechanics of the processes involved in indoor transmission of SARS-CoV-2 are discussed.
Journal ArticleDOI
A guideline to limit indoor airborne transmission of COVID-19.
Martin Z. Bazant,John W. M. Bush +1 more
TL;DR: In this paper, the authors derived an indoor safety guideline that would impose an upper bound on the cumulative exposure time, the product of the number of occupants and their time in an enclosed space, and demonstrate how this bound depends on the rates of ventilation and air filtration, dimensions of the room, breathing rate, respiratory activity and face mask use of its occupants.

How far droplets can move in indoor environments--revisiting the Wells evaporation-falling curve.
TL;DR: The results indicate that a droplet's size predominately dictates its evaporation and movement after being expelled, and there is a need to examine the air distribution systems in hospital wards for controlling both airborne and droplet-borne transmitted diseases.
