This paper, published in the International Journal of Indoor Environment and Health and produced by researchers funded under Theme 2 of the PROTECT study, details the development of a Computational Fluid Dynamics (CFD) model of droplets and aerosols to increase understanding of dispersion and deposition of respiratory emissions and implications for disease transmission.

The ability to model the dispersion of pathogens in exhaled breath is important for characterizing transmission of SARS-CoV-2 and other respiratory pathogens. A model of droplet and aerosol emission during exhalations has been developed and for the first time compared directly with experimental data for the dispersion of respiratory and oral bacteria from ten subjects coughing, speaking, and singing in a small unventilated room.
