“…Aeolian dust emission and undesired geomorphologic changes and dune morphology have driven many researchers to conduct extensive studies on wind erosion behavior (e.g., Borges and Viegas, 1988;Hesp, 2002;Diniega et al, 2010). Numerous wind tunnel tests and field observations have been carried out to analyze the deformation of stockpiles and sand transport phenomena (Zhou et al, 2002;Okoli, 2003;Ferreira and Lambert, 2011).…”

“…The open storage produces dust emission from aggregate piles, wind erosion being the main factor of the emissions. These emissions should be controlled and reduced as much as possible and a way to diminish them is to use windbreaks to protect the piles from wind erosion (Borges and Viegas, 1988;Jensen et al, 2001).…”

Experimental and numerical study of wind flow behind windbreaks AbstractThe shelter effect of a windbreak protects aggregate piles and provides a reduction of particle emissions in harbours. RANS (Reynolds-averaged Navier-Stokes equations) simulations using three variants of k-e (standard k-e, RNG k-e and realizable k-e) turbulence closure models have been performed to analyse wind flow characteristics behind an isolated fence located on a flat surface without roughness elements. The performance of the three turbulence models has been assessed by wind tunnel experiments. Cases of fences with different porosities (f ) have been evaluated using wind tunnel experiments as well as numerical simulations. The aim is to determine an optimum porosity for sheltering effect of an isolated windbreak. A value of 0.35 was found as the optimum value among the studied porosities (f = 0, 0.1, 0.24, 0.35, 0.4, 0.5).

“…Several researchers have developed multitude of techniques and methodologies to analyse the wind flow around the piles of open storage yards [1][2][3][4] and it is possible to buy standardised software to work out from quite simple to highly complicated simulations: ISC3, Aermod, Fluent, CFX, etc.…”

a b s t r a c tDust emission from storage yards is a multivariable problem to be solved not only at any new installation in order to obtain the licenses from the involved authorities but also at existing yards to continue the operation. Engineers have a great variety of methodologies available at the market to estimate such emissions, but in general the process is divided into two independent stages: wind flow analysis and application of emission rates into such wind pattern. This paper summarizes the research developed by this group to link both steps: by using CFX version 10.0, a powerful computational fluid dynamics (CFD) software, the wind flow around the piles is predicted, or even through a complex yard, and at the same time by implementing new subroutines introduced into the standard software, the program is able to give a quantitative evaluation of the total fugitive dust.
