cord-129086-ra2njvcz	Kumar, Sanjay	The perspective of fluid flow behavior of respiratory droplets and aerosols through the facemasks in context of SARS-CoV-2	2020-10-10		.txt	text/plain	8130	466	52	However, in more recent times, the focus has shifted towards the theoretical investigations of fluid flow mechanisms involved in the virus-laden particles prevention by facemasks. 44 While these experimental studies are essential for the broad characterization and design evaluation of respiratory facemasks, further theoretical and numerical methods and algorithm-based investigations provide a better insight into the facemask's fluid flow dynamics and the droplet leakage through the facemask openings. The computational fluid flow models have shown their potentials in an improved prediction of the spreading of respiratory virus-laden droplets and aerosols, sensitive to the ambient environment, and crucial to the public health responses. The results revealed that the small droplets travel a larger distance and remain suspended in the air for a longer time under the influence of airflow, supporting the mandatory use of facemasks to prevent the virus. In recent years, the respiratory droplets flow behavior through the facemasks has typically well-predicted using the computational fluid dynamics (CFD) techniques.	./cache/cord-129086-ra2njvcz.txt	./txt/cord-129086-ra2njvcz.txt
