Effects of nasal cavity and exhalation dynamics on aerosol spread in simulated respiratory events

Nicolás Catalán,
Salvatore Cito,
Sylvana Varela
et al.

Abstract: Coughing and sneezing are critical mechanisms for the transmission of airborne respiratory diseases, dispersing pathogen-laden aerosols into the environment. Previous human volunteer studies provided valuable insight into aerosol dynamics but lacked reproducibility due to individual variations. This paper presents a novel, replicable experimental setup using three dimensional models of the upper respiratory tract and nasal cavity to simulate isothermal human-like coughs and sneezes. Results indicate that nasal… Show more
