In this article, the authors summarized what we know and 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.Abstract:
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

Respiratory droplet resuspension near surfaces: Modeling and analysis
TL;DR: In this paper, a three-dimensional two-phase model is utilized to study respiratory droplet resuspension dynamics on various surfaces due to sudden agitation, and a parametric study is performed to characterize the effects of droplet size and surface wettability on the minimum initial droplet velocity required for detachment from surfaces.

Physiochemical hydrodynamics of the phase segregation in an evaporating binary microdroplet
TL;DR: Li et al. as discussed by the authors investigated the flow dynamics after the occurrence of phase segregation and revealed experimentally the overall physiochemical hydrodynamics of the evaporation process, including the segregative behaviour and the resulting flow structure close to the substrate.
