Numerical Validation of a Near-Field Fugitive Dust Model for Vehicles Moving on Unpaved Surfaces
Abstract
Vehicles moving on unpaved surfaces can be significant sources of fugitive dust emissions. The performance of vehicle operational characteristics as well as evaluating vehicle dust mitigation components including filters, radiators, seals, and windshields require models for the behavior and transport of emitted fugitive dust. Much of the work on modeling fugitive dust emissions from vehicles have focused on large scale atmospheric transport for environmental quality purposes. In this study, however, we present a dust emission and transport model suitable for modeling near-field effects of fugitive dust emissions. The presented model is validated numerically for the prediction of dust plumes in a region near vehicles through a careful comparison to the available experimental data. This model provides, for the first time, a validated dust emission and transport models suitable for the near field of moving vehicles. The weakness of the current near-field dust emission and transport technology is also discussed.
