Deposition Fractions of Submicron Aerosol Particles in an Air Sampling Pipeline

Abstract

To estimate the deposition fraction of submicron aerosol particles in a long sampling pipeline, an estimation equation was proposed and its applicability was experimentally verified. The equation proposed in this paper was found to give relatively good estimation of deposition fractions for submicron particles in both the laminar and the turbulent airflows. It was found that the deposition fractions from turbulent airflow could be obtained by considering a sampling pipeline composed of a horizontal, a vertical and a bent pipes with a total length.
