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

Controlling droplet splashing and bouncing by dielectrowetting
Miguel A. Quetzeri-Santiago,Miguel A. Quetzeri-Santiago,Jose Rafael Castrejon-Pita,Alfonso A. Castrejón-Pita +3 more
TL;DR: In this article, the authors demonstrate that dielectrowetting can be applied to actively control the dynamics of droplet impact and demonstrate that the dielectric effect is produced on a flat substrate by two thin interdigitated electrodes connected to an alternating current potential.

Aerosol Transport Modeling: The Key Link Between Lung Infections of Individuals and Populations
Chantal Darquenne,Azadeh A.T. Borojeni,Mitchel J. Colebank,M. Gregory Forest,Balázs G. Madas,Merryn H. Tawhai,Yilong Jiang +6 more
TL;DR: In this paper , the authors review existing data and models of generation of respiratory droplets and aerosols, their exhalation and inhalation, and the fate of infectious droplet transport and deposition throughout the respiratory tract, and articulate how aerosol transport modeling can serve as a bridge between and guide calibration of within-host and epidemiological models, forming a comprehensive tool to formulate and test hypotheses about respiratory tract exposure and infection within and between individuals.
