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

Topical Ocular Povidone-Iodine as an Adjunctive Preventative Practice in the Era of COVID-19.
TL;DR: Ophthalmologists and patients have an inherent increased risk for transmission of SARS-CoV-2 The human ocular surface expresses receptors and enzymes facilitating transmission of the SARS CoV2 Personal protective equipment alone provides incomplete protection.

COVID-19 dispersion in naturally-ventilated classrooms: a study on inlet-outlet characteristics
TL;DR: In this paper , the authors investigated the correlation between window height, natural ventilation, and COVID-19 dispersion in classrooms and found that stack ventilation and Bernoulli effect decrease indoor contaminant concentration.

TL;DR: While PFT can generate aerosols, it is less than normal speech with the exception of PFT-induced coughing, suggesting the risk of SARS-CoV-2 transmission is not increased and support the re-opening of P FT laboratories that adhere to universal masking, use of personal protective equipment and stringent infection control protocols.

Comparison between fully resolved and time-averaged simulations of particle cloud dispersion produced by a violent expiratory event
TL;DR: In this article , the authors compare the DNS results with those obtained with a compressible URANS equations with a k-ϵ turbulence model and find that the URANS model is capable of reproducing the observed tendency of light particles under 64 µm in diameter to rise due to the action of the drag exerted by the buoyant puff generated by the cough.

Non-Solvent Induced Phase Separation (NIPS) for Fabricating High Filtration Efficiency (FE) Polymeric Membranes for Face Mask and Air Filtration Applications
TL;DR: In this paper , single layer polysulfone (PSf) membranes were fabricated via non-solvent induced phase separation (NIPS) and were tested for airflow rate, pressure drop and FE.
