Saliva particles transport during normal breathing through mouth and nose

This talk presented a high-fidelity numerical investigation of saliva particle transport during normal breathing through the mouth and nose. Using large-eddy simulations and Lagrangian particle tracking, we analyzed how airflow structures in the upper airway influence particle dispersion and deposition patterns. The study highlighted key differences between oral and nasal breathing routes and discussed implications for airborne disease transmission and aerosol science. This work contributes to the broader understanding of respiratory particle dynamics in health and safety contexts.
