Windbreak Effectiveness for Storage-Pile Fugitive-Dust Control: A Wind Tunnel Study
Results of wind-tunnel experiments to determine the optimal size and location of porous windbreaks for controlling fugitive-dust emissions from storage piles in a simulated neutral atmospheric boundary layer are presented. Straight sections of windbreak material were placed upwind of two non-erodible, typically shaped piles and were also placed on the top of one of the piles. Wind speed, measured near the pile surface at various locations with heated thermistors, was isolated here as the primary factor affecting particle uptake. Wind speed distributions about the piles in the absence of any windbreak and the flow structure downwind of a three-dimensional porous windbreak are presented. Relative wind speed reduction factors are described and efficiencies based on the relationship between wind speed and particle uptake are given.
