Aerosol penetration relative to sentinel cage configuration and orientation.
Aerosol movement into 4 different sentinel cage configurations at 0 degrees, 30 degrees and 60 degrees orientation relative to the aerosol flow in a wind tunnel was studied using a quartz crystal microbalance cascade impactor. The data suggest that a cylinder, screened on all sides, with the longitudinal axis perpendicular to the ground would provide a consistent cage profile to the wind regardless of wind direction changes and thereby reduce aerosol environment variability among cages.
