An experimental study carried out by an international team of engineers and physicists has added more evidence for the value of masks made with three layers to prevent the spread of COVID-19 and similar diseases.
The results were published recently in Science Advances.
“Any form of the mask is better than no mask,” says study co-author Swetaprovo Chaudhuri, an associate professor at the University of Toronto Institute for Aerospace Studies in the Faculty of Applied Science & Engineering.

“But what we also show is that if they have enough momentum, large liquid droplets can penetrate single or even double-layer masks. When they do, they break up into smaller droplets that are more persistent in the air.”
The team – which also includes Assistant Professor Abhishek Saha at the University of California, San Diego and Professor Saptarshi Basu of the Indian Institute of Science – is leveraging expertise they developed while studying aircraft engines. They use computer models and physical experiments to understand finely dispersed droplets in air, known as aerosols.
In two previous papers, the team used models to describe the ways that droplets and aerosols created by a cough or sneeze can travel and persist in air. These mechanisms were then incorporated to develop a disease spread model – the first one to be developed from the flow physics of transmission.
