The dispersion of spherical droplets in source–sink flows and their relevance to the COVID-19 pandemic	2020-08-01		.txt	text/plain	6364	383	62	We find that, in the absence of gravity, there are two distinct behaviors for the droplets: small droplets cannot go further than a specific distance, which we determine analytically, from the source before getting pulled into the sink. The transport of inertial particles in fluid flows occurs in many problems arising in engineering and biology, such as the build-up of microplastics in the ocean 1 and respiratory virus transmission through tract droplets. 17 Such a flow could represent the trajectories of water droplets emitted from coughing, sneezing, [2] [3] [4] or breathing and in the presence of extraction, such as an air-conditioning unit or air current. We are interested in where the flow field changes direction, since this indicates the maximum distance the droplets emitted at the source can travel before moving toward the sink. We model the situation as a point source emitting droplets of various sizes in the presence of gravitational forces and compute the maximum horizontal distance traveled by these droplets.	./cache/cord-274781-tmc31aa6.txt	./txt/cord-274781-tmc31aa6.txt
