An analysis of the sensitivity of the rate of buoyancy-driven flame spread on a solid material to uncertainties in the pyrolysis and combustion properties. Is accurate prediction possible?

August 1, 2023
Author(s)
Yan Ding, Isaac Leventon, Stanislav Stoliarov
An upward, buoyancy-driven flame spread on combustible solids is frequently the dominant contributor to the growth of fire in built environment. Thus, an ability to accurately predict the development of a fire is strongly linked to the accuracy of flame

A Simulation Framework for Analyzing the Impact of Stochastic Occupant Behaviors on Demand Flexibility in Typical Commercial Buildings

Antonio Possolo, Amanda Koepke, David Newton, Michael R. Winchester
This contribution describes a Decision Tree intended to guide the selection of statistical models and data reduction procedures in key comparisons (KCs). The Decision Tree addresses a specific need of the Inorganic Analysis Working Group (IAWG) of the

Distribution of Earthquake Input Energy in Structures

January 1, 2003
Author(s)
P Khashaee, B Mohraz, Fahim H. Sadek, Hai S. Lew, John L. Gross
In developing an energy-based design approach and assessing the damage potential of structures, one must know the distribution of earthquake input energy among energy components: kinetic, elastic strain, hysteretic, and damping. This report examines the

Numerical Investigations of CO 2 as Fire Suppressing Agent

January 1, 2003
Author(s)
V Katta, F Takahashi, Gregory T. Linteris
Understanding suppression mechanisms of different fire-suppressing agents including CF 3Br (Halon 1301) and inert gases is useful for their efficient use and for developing new agents. Because of the similarities between unsteady jet diffusion flames

Bursting Bubbles From Combustion of Thermoplastic Materials in Microgravity

May 18, 1999
Author(s)
Kathryn M. Butler
Many thermoplastic materials in common use for a wide range of applications, including spacecraft, develop bubbles internally as they bum due to chemical reactions taking place within the bulk. These bubbles grow and migrate until they burst at the surface
