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

Quantitative analysis of particulate matter release during orthodontic procedures: a pilot study
Ahmed Riaz Din,Annika Hindocha,Tulsi Patel,Sanjana Sudarshan,Neil Cagney,Amine Koched,Jens Dominik Mueller,Noha Seoudi,Claire Morgan,Shakeel Shahdad,Padhraig S. Fleming +10 more
TL;DR: Particulate matter was released during orthodontic debonding, although the concentration and volume was markedly less than that associated with the use of a fast handpiece, and further research within alternative, open environments and without air exchange systems is required.

A novel strategy to fabricate stable oil foams with sucrose ester surfactant
Yu Liu,Bernard P. Binks +1 more
TL;DR: In this article, the effect of aeration temperature and surfactant concentration on foamability and foam stability of mixtures cooled from a one-phase oil solution was investigated and a strategy to increase foam stability by rapidly cooling foam prepared at high temperature was introduced.

Revisiting D 2 -law for the evaporation of dilute droplets
TL;DR: In this article, a revision of the D 2-law is proposed to accurately estimate the evaporation rate in dilute conditions by a proper estimate of the asymptotic droplet properties.

Modeling aerosol cloud aerodynamics during human coughing, talking, and breathing actions
TL;DR: From the simulation results, it can be concluded that the aerosols released due to continuous talking travel a similar distance to that releaseddue to sudden coughing, and aerosols exhaled from breathing do not travel a long distance but float in air for a long time.

Coupled population balance and large eddy simulation model for polydisperse droplet evolution in a turbulent round jet
Aditya Aiyer,Charles Meneveau +1 more
TL;DR: In this article, a hybrid approach is developed to simulate the transport and breakup of droplets in a turbulent round jet, where the inflow size distribution is obtained from a one-dimensional parcel model that is coupled to a coarse large-eddy simulation (LES) of a turbulent jet.
