Abstract

A clear understanding of the spatial distribution of dust will provide useful information to control dust sources, improve design of ventilation systems, and implement mitigation technologies. Numerical simulation will enhance the understanding of the mechanisms of dust transport within a ventilated airspace. A zonal mathematical model for dust spatial distribution was developed based on mass balance of particulate matter. The numerical simulation indicated that dust spatial distribution was highly related to the airflow pattern, dust source strength, and gravitational sedimentation of particles. Air distribution plays a major role in the transport of dust in a ventilated airspace. Validation of the model using measured data showed that the simulated overall mean dust concentrations were in close agreement with the measured values. The correlation coefficient (r) between the model simulation and measurements was 0.93.
