Analysis and Measurement of Candle Flame Shapes
(2008-05-07)A combined analytical and experimental study was performed to produce and validate a method by which the lengths and widths of flames burning on wax candles can be predicted. Two analogies are drawn: first, that heat ... -
ANALYSIS AND QUANTIFICATION OF HAZARDS ASSOCIATED WITH CASCADING THERMAL RUNAWAY PROPAGATION IN LITHIUM ION BATTERY CELL ARRAYS
(2018)Lithium ion batteries are among the most common and efficient electrical energy storage devices despite the thermal, fire, and chemical hazards they pose upon thermal failure due to abnormal conditions. The hazards are ... -
Analysis of Fire Conditions in a Closed-End Tunnel
(2004-05-18)Many studies have addressed fires in tunnels. For the most part, these previous studies have addressed fires that might occur during operation of the tunnel, when the tunnel has openings at both ends. During construction ... -
An Analysis of Heat Flux-Induced Arc Formation in Residential Electrical Cables
(2011)The mechanisms by which fire environments may trigger electrical arcs in household wiring are often misunderstood. A thorough knowledge of these mechanisms may assist fire investigators to determine whether a given arcing ... -
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 ... -
Analysis of Propane Gas Burner Experiments and FDS Simulations in a Two-Story Residential Structure with HVAC
(2020)To further our knowledge of fire dynamics in a residential structure with a heating, venitilation, and air conditioning (HVAC) system, a series of live fire gas burner experiments were conducted and modeling simulations ... -
Analysis of Propane Gas Fire Experiments and Simulations in Residential Scale Structures
(2017)Nine full-scale fire experiments were conducted in two residential-sized structures with a fire source provided by three propane gas burners. Five of the experiments were conducted in a single-story structure, and four ... -
Analysis of the Effects of Temperature and Velocity on the Response Time Index of Heat Detectors
(2010)Recent revisions to NFPA 72, the National Fire Alarm Code, have specified the response time index (RTI) as the sensitivity listing for heat detectors. Originally derived as a sprinkler sensitivity rating, there has been ... -
Analysis of the initial spray from canonical fire suppression nozzles
(2007-08-10)The performance of a fire suppression spray is governed by injector discharge characteristics. An atomization model based on the theoretical evolution of a radially expanding sheet generated by an impinging jet has been ... -
THE ANALYSIS OF THE TRANSITION FROM SMOLDERING TO FLAMING IN POLYURETHANE CONTAINING ASSEMBLIES REPRESENTATIVE OF UPHOLSTERED FURNITURE
(2019)The smoldering and ignition of upholstered furniture is the leading cause of loss of life in accidental residential fires. Due to these fatal incidents, a new smoldering apparatus experimental setup was designed and built ... -
An Analysis of Thermally Induced Arcing Failure of Electrical Cable
(2013)Arc failure of Southwire Romex Simpull non-metallic sheathed 14/2 American wire gauge (AWG) with ground cable due to external heat was examined. This type of cable was selected due to its widespread use in residential ... -
Analysis of Underventilated Compartment Fires
(2009)Little research has been done to examine full-scale unventilated fires despite their common occurrence and relevance. This project was conducted to characterize the fire dynamics of unventilated and partially ventilated ... -
An Analysis of Vehicle Fires and Potential Methods to Reduce Their Severity Through More Stringent Material Standards
(2008-06-17)In the United States, more than 1 in every 12 fire fatalities occurs in a passenger road vehicle; vehicle fires claim roughly 1200 injuries, $1.3 billion in property loss, and 490 lives annually. Very little progress has ... -
Analyzing Photo-Electric Smoke Detector Response Based On Aspirated Smoke Detector Obscuration
(2010)Accurate obscuration levels at the response time of photo-electric smoke detectors are needed for proper detection modeling and analysis. In recent works, obscuration meters were used to measure the obscuration level at ... -
Assessing the Validity of the Verification Method as a Design Tool
(2018)The Verification Method (VM) as a design tool is becoming more widespread, result-ing in a need for a critique of the concepts behind the method. This project provides the critique by extracting examples from the design ... -
Assessment of Duct Leakage Rates on Stairwell Pressurization System
(2014)This study aims to evaluate the effects duct leakage had on a stairwell pressurization system in a high-rise residential building by using a network model, CONTAM. The network model was used to determine if the pressurized ... -
ASSESSMENT OF NATURAL VERTICAL VENTILATION FOR SMOKE AND HOT GAS LAYER CONTROL IN A RESIDENTIAL SCALE STRUCTURE
(2012)In firefighting, ventilation tactics are used to increase visibility for firefighter rescue and fire suppression operations, to increase survivability of the occupants of the structure, and to decrease property damage. ... -
An Assessment of the Use of Flame Retardant Plastics for Museum Applications
(2007-12-18)Halogenated flame retardant plastic sheeting may help to reduce flame spread in museums; however, the plastics contain chemicals that may be harmful to museum objects in situ, particularly metals. This study assesses ... -
