By now, we all know the basic coronavirus rules. Wear a mask, limit your exposure to other people and when you can’t, keep your distance, and … keep wearing your mask. But what we haven’t known is whether we should keep the car windows up or down.
A new study from Brown University seeks to answer that question. Using complex computational fluid dynamic simulations, Varghese Mathai, Asimanshu Das, Jeffrey Bailey and Kenneth Breuer studied how the aerosols that we breath (some of which do escape even properly worn masks) move about a car’s cabin and how those flows change with various windows up and down.
The details of the study are worth noting. The team of researchers found that opening the windows opposite of each occupant can create a flow that drastically reduces the collection of aerosols in a car’s cabin. They also found that opening the windows even halfway can be very helpful but that just cracking them a bit doesn’t generate enough airflow.
