Chong Shen Ng, University of Twente and Max Planck Center for Complex Fluid Dynamics, sat down with the Physical Review Journal Club for an important discussion of the recently-published Physical Review Fluids paper: "Growth of respiratory droplets in cold and humid air."
Throughout the COVID-19 pandemic, much attention has been focused on respiratory droplets produced by breathing, coughing, and singing. According to Ng and co-authors' numerical simulations of a cough, droplets first grow before evaporating and shrinking in cooler, more humid air—they don’t continuously evaporate, as previous research has suggested. The growth occurs when warm, humid breath interacts with colder air, producing a plume of water-vapor-saturated air—an effect that leads to the familiar “frosty” breath on cold days. The enlargement of cough droplets inside this plume causes them to survive longer than they do at higher temperatures, potentially allowing an infected person to spread an airborne disease to people located farther away.
Ng provided a brief presentation of these results and answered questions during a discussion session moderated by Emmanuel Villermaux, Aix-Marseille Université, Marseille, France.
