Three Pulse Cough

Caption

Visualizations showing a snapshot of (top to bottom) single-, two-, and three-pulse coughing events. Colors show "fluid vorticity," or rotation. Vortex structures can be seen to persist closer to the mouth for two- and three-pulse cases. These swirls can accelerate particles and send them further from their source than typical cough models would predict. This is especially important because air in these later pulses comes from deeper in the lungs and, in the case of COVID-19, would likely carry higher viral load.
