WebJan 3, 2024 · In terms of experimental studies, the transient velocity distribution and width of cough airflow have been measured using methods such as the particle image velocimetry (PIV) technique. A maximum velocity range of 6–28 m/s has been detected, and the cough was found to expand linearly in the initial stage [6, 7, 11–13]. WebPenetration Distance and Velocity Field of a Cough Jet. The hot-wire anemometer measured the velocity profile of the cough jet with a discharge velocity of 6.08 m/s at the center of the source opening. The velocity distribution across the source opening follows the velocity profile of a fully developed turbulent pipe flow.
