摘要: The fluid mechanics of aerosols is reviewed and forces responsible for migration, dispersion wall deposition contaminant particles are discussed. A digital simulation procedure studying from turbulent air streams on different surfaces presented. Effects Brownian diffusion, Saffman lift force gravity included in the computational model. Approximate exact methodologies instantaneous fluctuating velocity components a stream described. simulating motion submicrometer also Examples aerosol range 0.01 to 10 μm initially uniform concentrations point sources
