Ever been on a flight, hear someone sneeze, and then sit in fear as you imagine millions of tiny infectiousness germs laughing historically as they spread through the cabin of the plane? In my imagination they are green and drip mucus. In reality they are small liquid particles and instead of going everywhere, it appears they fall on just a few unlucky people.
ANSYS, Inc. put out a very cool video showing the results of an in-cabin CFD run done by Purdue University that tracks the pathogens as they leave the sick persons mouth, get caught in the climate control system’s air stream, and waft right on the people next to and behind them. The study was done for the FAA Center for Excellence for Airliner Cabin Environment Research.
Here is the video, check it out and share with your friends. Especially if you have a friend that doesn’t sneezes out into the open air:
