Description:
Fugitive dust emissions from stockpiles in the open storage yards of industrial sites and the subsequent atmospheric dust dispersion have brought about many ecological and economical problems. This paper introduces a new approach to estimate emission rates using data from Computational Fluid Dynamics simulations. Flow around stockpiles of varying configurations was studied using a previously validated numerical model. Different pile height scenarios, corresponding to a constant material volume and a fixed angle of repose, were exposed to various wind speeds. Flow analysis over the piles showed the importance of using 3D simulations to fully understand the close linkage between flow processes and particles uptake. Data obtained were then integrated in order to evaluate dust emission rates. Results provide evidence to suggest that changing pile configuration can reduce dust emissions. It was found that, for the range of wind conditions and pile dimensions tested, the intermediate pile height configurations lead to a better overall protecting effect from wind and thus were found to produce lower dust emissions.
