5408 Prediction of Pollen Flow Behavior with Saltation and Suspension over Surface
Details
In the investigation of pollinosis, it is often reported that the rate of appearance of pollinosis is higher in the city than in the country and the patients with pollinosis increase along with urbanization. The main causes of these results are secondary scatter of pollen. Almost all the surface in the city are paved and the pollen on the surface is blown up by the strong wind which flows around the tall buildings. In this paper, the flow behavior of pollen with secondary scatter is studied by the wind tunnel experiment and numerical calculation. The numerically calculated velocity profiles agree very well with the experimentally measured one, and the mean flow behavior of pollen can be predicted by this calculation.
