Predicting Breathing Zone Concentrations of Aerosols Dispersed in a Time-Dependent Airflow Using Vortex Methods

• Description:
  The most significant conclusion from this work is that the rate of accumulation of pariculate matter within the BZ is strongly dependent upon the distance between the contaminant source and the body. The results also suggest that particle concentration levels within the BZ may also rely heavily on source distance; however, it is impossible to draw any strict conclusions about this relationship until steady-state concentrations have been attained. Simulations with 7.5x10·1 m and 1.0 m injection sites must be run for a longer period of time. No clear relationship between particle size and concentration level could be discerned from the results.
