Abstract |
A numerical model was developed to describe the effect of aerosol source and airflow conditions on the dispersion and local exhaust capture of aerosol contaminants. Parameters discussed include particle diameter, density and initial velocity, the influence of obstacles and airflow patterns, particle relaxation time, aerodynamic diameter, and stopping distance. It was concluded that local exhaust capture of passively emitted particles can be described by particle relaxation time and the vertical air velocity at the emission point. The influence of particle initial velocity is limited compared to imposed airflow conditions. |
