Numerical Investigation of Cough Droplets Dispersion Dynamics in Indoor Environment: Effect of Oral Cavity Shape
This study focused on the impact of the reproduction of oral cavity shape on the droplets dispersion dynamics, and compared the coughing dynamics between human models with and without oral cavity by using computational fluid dyanmics (CFD) technique. In this analysis, droplets were released from mouth opening surface or from the trachea via oral cavity. The results showed these models made differences of exhaled airflow pattern, the droplets dispersion and the rate of inhalation and deposition depending on the oral cavity shape. In conclusion, the droplets dispersion dynamics with consideration of oral cavity shape might contribute to accurately predict the dispersion characteristics of droplets and infection risk caused by coughing.
