Flame Extinction and Air Vitiation Effects In FDS In Poorly Ventilated Compartment Fires
(2005-08-15)
Compartment fires with different ventilation conditions exhibit different dynamical behaviors, ranging from steady fuel-limited fires to unsteady air-limited fires. Numerical simulations are here performed to study compartment ...
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. ...
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 ...
Evaluation of Fire Dynamics Simulator for Liquefied Natural Gas Vapor Dispersion Hazards
(2011)
The Federal Energy Regulatory Commission (FERC) and Pipeline and Hazardous Material Administration (PHMSA) require vapor dispersion modeling as part of a siting analysis for liquefied natural gas (LNG) facilities. Guidance ...
Numerical modeling of full scale limited ventilation fire tests
(2008)
Underventilated enclosure fires represent one of the largest causes of fire fatalities and understanding their behavior is of great interest. The newest major release of the Fire Dynamics Simulator (FDS) has made significant ...
Smoke Characterization of Incipient Fire Sources for FDS Modeling
(2008-08-29)
This thesis describes the experimental and analytical methods used to characterize the heat and smoke release rates of eight different incipient fire sources. These characterizations are part of a larger effort to evaluate ...
Numerical Simulation of Ignition and Transient Combustion in Fuel Vapor Clouds
(2007-07-31)
The Large-Eddy Simulation (LES) approach is used to model partially-premixed combustion (PPC) in confined and unconfined fuel vapor clouds. The model is based on the concept of a filtered reaction progress variable to ...
Simulating the Fuel Mass Loss Rate in Fire Dynamics Simulator (FDS) Using a New Furniture Calorimeter
(2010)
Fire Dynamics Simulator (FDS) is widely used in the fire community to simulate and understand in detail enclosure fire dynamics. Fire models require accurate descriptions of the fuel sources to simulate the fire behavior. ...
VERIFICATION AND VALIDATION OF A CANDIDATE SOOT DEPOSITION MODEL IN FIRE DYNAMICS SIMULATOR VERSION 5.5.1
(2010)
Deposition of soot generated from fires is important for tenability, smoke management, detector response, and fire forensics. Previous versions of Fire Dynamics Simulator (FDS) did not account for soot deposition, but FDS ...
A Generalized Model for Wall Flame Heat Flux During Upward Flame Spread on Polymers
(2015)
A current model accurately predicts flame to surface heat flux during upward flame spread on PMMA based on a single input parameter, the mass loss rate. In this study, the model was generalized to predict the heat flux for ...
