Abstract
ABSTRACT
A quantitative theory (Eisner et al., 1990) that has been developed to predict coupled mass and energy transport phenomena during breathing of high volume hygroscopic aerosols has been applied to simulate exhalation (as well as inhalation) under different boundary conditions. It is shown that wall temperature may influence particle/vapor interaction, but the impact appears to be stronger at low particle concentration. At the same time, aerosol-induced (on the particle surface) vapor evaporation and condensation at high particle concentrations will influence strongly the air temperature and relative humidity patterns within the respiratory system.
