Simulation showing how wearing masks can improve airline passenger safety.

This simulation aims to replicate the physical behaviour of air-borne droplets under realistic conditions in a modern aircraft, allowing for air conditioning. Two people seated on the same row are having a 3-minute conversation, with the person who is speaking shown in red.   The arrows show the flows of air within the cabin and the colour concentration of droplets from the respiratory tract (mouth and nose) that have accumulated on a surface or person. During the full conversation of 180 seconds, the mask is shown to reduce the number of droplets released into the airline cabin significantly. Blue indicates no accumulation, and red high accumulation, of exhausted droplets after 180 seconds.  The droplet accumulation at this close proximity shows how wearing a face mask improves air travel safety when there is a risk of airborne infection. Please follow the guidance from relevant authorities. It is not a piece of medical advice.  See how public research was used to create this simulation using Cradle CFD software at -
