AN INVESTIGATION ON THERMAL CHARACTERISTICS OF PREMIXED COUNTERFLOW FLAMES USING MICRO-THERMOCOUPLES
(2005-05-03)
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 ...
Development of Video Image Detection Algorithm for Smoke Plumes
(2007-07-03)
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 ...
Evaluation of the Ability of Fire Dynamic Simulator to Simulate Positive Pressure Ventilation in the Laboratory and Practical Scenarios
(2005-12-13)
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 ...
Analysis of Hold Times for Gaseous Fire Suppression Agents in Total Flooding Applications
(2005-08-12)
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 ...
NITROGEN FOAM FIRE SUPPRESSION SYTEM FOR AUTOMOBILE UNDER-HOOD POST-COLLISION FIRE PROTECTION
(2004-08-19)
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 ...
Predicting Smoke Detector Responce Using a Quantitative Salt-Water Modeling Technique
(2004-06-16)
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 ...
Characterization of the MIL-F-24385F Nozzle
(2005-01-25)
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. ...
Atomization Model Development for Fire Suppression Devices
(2005-05-04)
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 ...
Quenching Limits and Materials Degradation of Hydrogen Diffusion Flames
(2008-04-25)
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 ...
EXPERIMENTAL AND NUMERICAL CHARACTERISTICS OF SOIL RESPONSE TO INTENSE HEATING
(2008-03-14)
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 ...
