Simulation Study of Dust Spatial and Temporal Distribution in Dry Bulk Cargo Port Yard Based on Production Operation Characteristics

Recently, with the continuous development of the dry bulk shipping market, dry bulk ports remain busy, and dust pollution has become severe. Considering the production operation characteristics in dry bulk cargo port areas, an AERMOD-based simulation model is established in this paper, aiming to study the spatial and temporal distribution of dust in yards under different storage strategies and various surface water contents of dry bulk cargo. The results show that the dust intensity is 33.6% higher when the production operation characteristics are taken into account, dispersing dry bulk cargo with high dust intensity can effectively reduce the overall dust intensity of the yard, and keeping the surface water content of dry bulk cargo at 6%–8% has the best economic benefit. This study provides decision support for the development of storage strategies and dust suppression measures in dry bulk port yards.
