Experimental and Analytical Study on the Particulate Entrainment and Dispersion From a Porous Emission Source in Wind

General particulate entrainment mechanisms and dispersion of entrained particulates from a porous emission source in wind such as storage pile are studied. The mechanisms of particulate entrainment and downwind particulate dispersion are experimentally determined with the use of two porous pile models of different heights: a 51 mm high model and a 76 mm high model. The reduction of blowing velocity on the surface of the source is illustrated by the proper use of the windbreaks located at approximately two to three pile heights upstream. The tracers used in the experiment are smoke, magnesia, latex, and glass particles. The scaling results based on the measured data indicate that the effect of particle settling due to gravity force will be significant when the particle settling velocity is greater than 0.03 m/s.
