Flame Extinction and Air Vitiation Effects In FDS In Poorly Ventilated Compartment Fires
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 fires in a configuration corresponding to a scaled-down model… Contents CHAPTER I: INTRODUCTION 1.1 OVERVIEW 1.2 LITERATURE REVIEW 1.3 RESEARCH OBJECTIVE CHAPTER II: MODEL DESCRIPTION 2.1 FDS COMBUSTION [...]
Scale Modeling of the Transient Behavior of Wood Crib Fires in Enclosures
Scale modeling affords engineers the ability to appreciate the dynamic enclosure fire environment of larger than life structures in the laboratory. Conventional approaches to scaling have expressed results in terms of time-averaged values… Author: Perricone, Jonathan Andrew Source: University of Maryland Download This Report (PDF) Download URL 2: Visit Now Download URL 3: Visit Now
Inverse fire modeling to estimate the heat release rate of compartment fires
The objective of this research is to develop a new paradigm in fire-fighting techniques and demonstrate the feasibility of using fire imaging technology (e.g., thermal imaging cameras to monitor smoke conditions from a burning building) combined with fire modeling software for real-time fire analysis to assist firefighter operations. This project focuses on the development of [...]
Fire Safety of Today’s and Tomorrow’s Vehicles
This thesis considers fire hazards in the existing vehicle fleet and uses failure modes and effects analyses of three generic designs to identify and rank potential fire hazards in the Emerging Fuel Vehicle (EFV) fleet. A statistics based predictive quantitative risk assessment framework and estimated uncertainty analysis is presented to predict risk of EFV fleets.. [...]
Characterizing Cigarette Lighter Flames to Reduce Unwanted Ignition
This investigation provides detailed measurements and analysis for improved understanding of ignition from the ‘small’ flames produced by cigarette lighters. This research program is motivated by the need to improve the fire safety of cigarette lighters in response to the juvenile firesetter problem… Contents Chapter 1: Introduction 1.1 Overview 1.2 Literature Review 1.3 Objectives Chapter [...]
Predicting thermally thin burning of polymer using TGA/DSC
The flammability properties of pure Nylon 6 and Nylon with nano-clay of 5 % are examined in this study, TGA/DSC data were obtained with a variety of heating rates. The decomposition rate was found from the analysis of TGA data based on the mass loss fraction. The rate of reaction was described by a first-order [...]

Critical Behavior of Long Span Cellular Beams in Fire
This paper presents an investigation of the structural response of a long span cellular beam with varying section geometries while subject to various temperature-time curves. This type of beam is under investigation, in part, because of its increased use in long span building construction and its unique thermal response when protected with intumescent coatings; but [...]
