Wind Tunnel Modeling Of The Jack Rabbit Ii Mock Urban Environment Chlorine Releases Based On Comparison With Field Scale Video Record, Samuel Gallimore Aug 2023

Wind Tunnel Modeling Of The Jack Rabbit Ii Mock Urban Environment Chlorine Releases Based On Comparison With Field Scale Video Record, Samuel Gallimore

Graduate Theses and Dissertations

Unintentional releases of hazardous gases have led to significant injuries and fatalities in severe cases. Field tests can be used to release hazardous gases to document and evaluate the behavior of the gases. Chlorine is an especially hazardous gas due to its toxicity. The Jack Rabbit II Phase I field tests released chlorine within a mock urban environment (MUE) consisting of Conex containers arranged in rows to simulate buildings and streets. The number of field tests is limited by both expense and time. Simulation of a field test using a wind tunnel model can provide additional data and opportunity for …


Measuring Plume Concentration Variations Under Neutral Atmospheric Conditions, Daniel Williams May 2023

Measuring Plume Concentration Variations Under Neutral Atmospheric Conditions, Daniel Williams

Chemical Engineering Undergraduate Honors Theses

Hazardous gases are increasingly becoming a large safety concern as the world continues to grow and industrialize. The modeling of when hazardous gases breach containment is an extremely important objective of consequence assessment planning and response. To improve the understanding of the variability inherent in passive gas releases, a test program to demonstrate the variability of gas concentration measurements at different location in a passive gas plume released from an area source in the ultra-low speed wind tunnel at the Chemical Hazards Research Center. A Flame Ionization Detector was used to measure the concentration of the source cloud. Methane was …
