Abstract |
A general mathematical model describing the motion of particles in aerosol centrifuges has been developed. It has been validated by comparisons of theoretically predicted calibration sites with experimental data from tests sizing aerosols in instruments of three different spiral duct configurations. By accurately simulating factors which influence centrifuge performance, the model enhances the versatility of existing instruments and promotes CAD (computer aided design) and CAM (computer aided manufacture) of new units. The model will permit more accurate aerodynamic classifications of airborne particles. Therefore, more precise determinations of deposition sites of inhaled aerosols within the lung will be possible, since such locations are primarily functions on the dynamic characteristics of motion. U.S. EPA risk assessment protocols of pollutant aerosols will thereby be improved. (Copyright (c) 1989, American Industrial Hygiene Association.) |
