DEPOSITION OF PARTICLES FROM TURBULENT FLOW IN THE FREE ATMOSPHERE.

Research output: Contribution to journalConference article

Abstract

Recent interest in air pollution modeling has focused attention on the subject of dry deposition from the free atmosphere. Accurate knowledge of deposition is important when determining the ultimate fate of emitted particles and gases, when predicting contamination of surfaces exposed to air pollutants, and when conducting mass balance studies for a given region. While deposition of a gaseous species depends on the ability of a surface to react with the gas, particle transport is generally governed by aerodynamic factors. This study focuses on the aerodynamics of particle deposition from the atmosphere, based on a review of the literature. The primary focus concerns theoretical models for rough vegetated surfaces. However, the principles summarized here can be readily applied to other rough or smooth surfaces.
