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

Airborne particle dispersion by high flow nasal oxygen: An experimental and CFD analysis
TL;DR: A multi-faceted approach was taken to studying the aerosol-laden exhalation jet and showed that small droplets were most greatly affected, where a 1 m/s increase in velocity and 1 s increase in duration caused an 80% increase in axial travel distance.

Three-dimensional simulation of clouds of multi-disperse evaporating saliva droplets in a train cabin.
TL;DR: In this paper, the dispersion of evaporating saliva droplets in the cabin of an interregional train was investigated and a relevant physical model was constructed taking into account the state of the art in terms of existing paradigms and their ability to represent some fundamental aspects related to the evolution in time of a cloud of multi-disperse droplets.
