Abstract
Abstract—An experimental study of cough airflow fields
produced by subjects who were presumed to be ill with
influenza was conducted. Particle image velocimetry (PIV) and
hot wire anemometry (HWA) measurements were taken in the
far-field downstream of the mouth of a participant. Droplet
sampling was performed at two locations within a large cough
chamber, and a nasal swab confirmed the presence of an
infection. The present work analyzes data from two separate
cohorts, and modest differences were observed between coughs
from sick and convalescent participants. The results are also
compared to data obtained from a large eddy simulation (LES)
which seeks to model the transient behaviour of a human cough.
