Enhancing Egress Drills: Preparation and Assessment of Evacuee Performance

July 11, 2017
Author(s)
Steve Gwynne, Erica D. Kuligowski, Karen E. Boyce, Daniel Nilsson, Amanda Robbins, Ruggiero Lovreglio, J.R. Thomas, A. Roy-Poirier
This article explores how egress drills - specifically those related to fire incidents - are currently employed, their impact on safety levels, and the insights gained from them. It is suggested that neither the merits of egress drills are well understood

Flame Inhibition by Potassium-Containing Compounds

June 30, 2017
Author(s)
Valeri I. Babushok, Gregory T. Linteris, Pol Hoorelbeke
A kinetic model of inhibition by the potassium containing compound potassium bicarbonate is suggested. The model is based on the previous work concerning kinetic studies of suppression of secondary flashes, inhibition by alkali metals and the studies of

Modeling flame extinction and reignition in large eddy simulations with fast chemistry

May 16, 2017
Author(s)
James White, Sebastien Vilfayeau, Andre Marshall, Arnaud Trouve, Randall McDermott
This work seeks to support the validation of large eddy simulation (LES) models used to simulate the response of fires to the activation of a suppression system. The emphasis in the present study is on the prediction of flame weakening and extinction when

LOW-GWP REFRIGERANTS: PERFORMANCE ASSESSMENT AND SELECTION TRADEOFFS

April 23, 2017
Author(s)
Piotr Domanski, Riccardo Brignoli, J S. Brown, Andrei Kazakov, Mark McLinden
The merits of an alternative refrigerant are established based on many attributes including environmental acceptance, chemical stability in the refrigeration system, low toxicity, flammability, efficiency and volumetric capacity. In an earlier work, these

A Generalized Model of Flame to Surface Heat Feedback for Laminar Wall Flames

March 7, 2017
Author(s)
Isaac T. Leventon, Stanislav I. Stoliarov, Kevin T. Korver
In this work, experimental measurements of flame heat flux and sample mass loss rate are obtained as a flame spreads vertically upward over the surface of seven commonly used polymeric materials, two of which are glass reinforced composites. Using these

Propane Gas Fire Experiments in Residential Scale Structures

February 27, 2017
Author(s)
Joseph M. Willi
Nine full-scale fire experiments were conducted in two residential-scale structures to study how different fire fighting tactics, specifically horizontal, vertical, and positive pressure ventilation, affect the fire environment within a structure. The fire

A Boolean Approach to Modeling Logical Constraints

February 19, 2017
Author(s)
L I. Schultz
This paper presents a method that uses Boolean logic to model complex logical constraints in a zero-one integer programming optimization. The article examines how the problem of inding a least-cost plan of compliance with building fire codes can be modeled

A Comparison of Quality of Dispersion of Single Wall Carbon Nanotubes Using Different Surfactants and Biomolecules

February 19, 2017
Author(s)
Jeffrey W. Gilman, R Haggenmueller, Sameer Rahatekar, Jeffrey Fagan, Jae H. Chun, Matthew Becker, Rajesh R. Naik, Todd Krauss, Lisa Carlson, Shana O. Kelley, Paul C. Trulove, D M. Fox, John Kadla
The application of single wall carbon nanotubes (SWCNT) in current and future applications crucially depends on the ability to process SWCNT in a solvent to yield high quality dispersions characterized by individual SWCNTs and possessing a minimum of SWCNT

A Direct Error Measure for Affine Models of Nonlinear Algebraic Systems

February 19, 2017
Author(s)
D M. Lorenzetti
This paper proposes a measure of the deviation between a nonlinear equation and its affine model, and demonstrates applications to nonlinear systems. The measure expresses the model error relative to a representative change in its predicted value
