Abstract
Understanding of droplet nuclei dispersion and transport characteristics can provide more engineering strategies to control transmission of airborne diseases. Droplet dispersions in a room under the conventional well-mixed and displacement ventilation were simulated. A single droplet nuclei size of 10 mm was selected. The flow field was modeled using k-e RNG model. A new Eulerian drift-flux methodology was employed to model droplet phase. Under the conventional ventilation scheme, the droplets were homogeneously dispersed within approximately 50s. Droplet nuclei exhibit distinctive dispersion behavior, particularly for low airflow microenvironment.
