Abstract |
A quantitative theory has been developed to predict coupled energy and mass transport phenomena during inhalation of hydroscopic aerosol-laden air. It is shown that hygroscopic particle-induced vapor scavenging will influence temperature and relative humidity patterns within the respiratory system. Consequently, particle growth kinetics will depend on its number concentration. Monodisperse hygroscopic aerosol will become polydisperse and stratified, which may subsequently affect the deposition probabilities. (Copyright (c) 1990 Pergamon Press.) |
