Investigation into particle collection efficiency of circular cylinders imitating gauze fibers by CFD

Abstract

The dry gauze method, which uses gauze embedded in a wooden frame, is often used to evaluate the amount of airborne salt. However, the scattering behavior of particles around the collection device and the deposition mechanism to the gauze fibers has not been studied in detail. In this study, to study the relationship between the collected salinity by this method and the actual atmospheric salinity, the particle collection efficiency of single gauze fiber was investigated based on the flow fields around the circular cylinders by CFD. The result shows that the particle collection efficiency of circular cylinders depends on the Reynolds number, particle size, and the distance between the cylinders.
