Hydrogen addition is known to improve the stability of highly strained hydrocarbon premixed flames. Since the flame temperature is an important factor associated with extinction, it is of interest to study the thermal ...

The objective of this work is to develop a predictive activation time algorithm for smoke plumes for axonX's SigniFire video image detection (VID) system from recent tests in a large volume space performed at the University ...

Positive Pressure Ventilation (PPV) is a tactic that is used on fire grounds across the world everyday, both to improve tenability after the extinguishment of a fire and/or offensively during fire attack to improve ...

Many of the clean agents currently used in total flooding fire suppression applications have vapor densities greater than ambient air. The denser agent-air mixture creates hydrostatic pressure differences causing flow of ...

This thesis describes the development and testing of a Nitrogen Foam fire suppression system. The purpose of the system is to contain or extinguish fires that originate in the engine compartments of automobiles after ...

This investigation provides a detailed analysis of the hydraulic analogue technique used as a predictive tool for understanding smoke detector response within a complex enclosure. There currently exists no collectively ...

Aqueous Film Forming Foam has been a fire suppression agent in use for nearly forty years. During this period, there has been little emphasis on characterizing the flow from nozzles that have a throw of only a few meters. ...

The performance of water-based fire suppression systems is governed by the dispersion of the droplets in the spray. Characterization of the spray is essential for predicting and evaluating the performance of these suppression ...

This study examines the types of hydrogen leaks that can support combustion and the effects on various materials of long term hydrogen flame exposure. Experimental and analytical work is presented. Measurements included ...

This work investigates the thermal transient response of different soils when exposed to intense heat flux. A special porous media code, TOUGH2, is applied for numerical analyses. Improvements are made to previous experimental ...
