Varghese Mathai is a physicist at the University of Massachusetts at Amherst who conducted a study using computational fluid dynamics simulations to understand how air flows inside a car and its implications for COVID-19 airborne transmission.
In this interview, he explains the optimal ways to ensure maximum airflow inside a car and what can be done to reduce the risk of airborne transmission.
“It’s important to have good ventilation. This means you get as much outside air as possible to mix with the air inside the cabin and then flush it out,” says Mathai. ”You can do this in a couple of ways. One is by turning on the heating system, which takes in fresh air from outside, and opening windows through which it can be flushed out.
