Growth Of Diesel Exhaust Particulate Matter In A Ventilated Mine Tunnel, Glen A. Wilt

Graduate Theses, Dissertations, and Problem Reports

The objective of this work was to study the formation and evolutionary characteristics of aerosols, originating from the exhaust plume of a diesel engine operating in a ventilated mine tunnel. To extract these characteristics, precise cross-sectional scalar exhaust maps of CO2, temperature, and aerosol concentration were generated and used to track the time averaged axial development of the plume. These maps were then used to position aerosol size distribution samples within critical regions of the plume. This approach was found to provide an efficient and thorough record of aerosol formation and evolution, as a result of naturally dispersed diesel exhaust …
