Abstract
Highlights
•Noninvasive schlieren technique was applied to characterize human exhalation.
•New methods were proposed to predict exhaled velocity um and up, respectively.
•Potential infection risk depended on breathing patterns and spatial distribution of exhaled air.
•New data was added to airflow dynamics of human breathing and CFD boundary settings.
