Abstract

Abstract

In the paper, the chemical and physical characteristics of sodium aerosol particles as well as factors that influence the sedimentation rate of sodium aerosol during its transport are analyzed. Besides, a simplified model is given to calculate the sedimentation rate when aerosol getting through the emergency ventilation system. It has been found that the sedimentation rate is largely determined by gravity, turbulent coagulation and turbulent, other factors, such as brownian diffusion, could be ignored.
