Condensation (Chapter 15)

January 1, 2003
Author(s)
Mark A. Kedzierski, J C. Chato, T J. Rabas
Condensation is the process by which a vapor is converted to its liquid state. Because fo the large internal energy difference between the liquid and vapor states, a significant amount of heat can be released during the condensation process. For this

DEMONSTRATING ENHANCED POWDER PANELS

January 1, 2003
Author(s)
D C. Cyphers, Scott A. Frederick, John P. Haas
Recent investigations have been conducted into effective, lightweight, non-halon fire protection techniques for mitigating aircraft vulnerability to ballistic threat-induced fires. This paper describes investigations to identify and demonstrate enhanced

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

Extinction Characteristics of Cup-Burner Flame in Microgravity

January 1, 2003
Author(s)
V Katta, F Takahashi, Gregory T. Linteris
Carbon dioxide extinguishes flames through dilution process. The extinction characteristics of CO2 were previously studied using a cup-burner flame under normal-gravity conditions. As the diffusion flames behave differently in microgravity compared to

Fluoroalkyl Phosphorus Compounds

January 1, 2003
Author(s)
J D. Mather, R E. Tapscott, J M. Shreeve, R P. Singh
In work sponsored by the Next-Generation Fire Suppression Technology Program, research efforts at the New Mexico Engineering Research Institute extended earlier promising studies on alkyl phosphorus compound flame extinguishment performance to the study of

Improvements to the NIST Fire Dynamics Simulator

January 1, 2003
Author(s)
Kevin B. McGrattan, J E. Floyd, Glenn P. Forney, Howard R. Baum, Simo A. Hostikka
A new version of the NIST Fire Dynamics Simulator (FDS) was released in the fall of 2001. Improvements have been made to the combustion and radiation routines, allowing for better simulation of flashover. The combustion is based on a single transport

MatML Version 3.0 - Schema

January 1, 2003
Author(s)
E F. Begley
This document contains the formal specification of MatML Version 3.0 - Schema in World Wide Web Schema Definintion Language and is an update of the previously released Annotated MatML DTD Working Draft Version 2.0. This update addresses the technical

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

PHASE DOPPLER MEASUREMENTS OF LIQUID AGENT TRANSPORT OVER A HEATED CYLINDER

January 1, 2003
Author(s)
Cary Presser, Charles T. Avedisian, B S. Johnson
Experimental results are presented for a well-characterized, droplet-laden homogenous turbulent flow field around a cylindrical obstacle. Liquid agent transport was investigated around an unheated and heated cylinder under ambient conditions. Results for

Potential Benefits of Smart Refrigerant Distributors

January 1, 2003
Author(s)
William V. Payne, Piotr A. Domanski
The main goal of this study was to investigate the benefits possible for finned tube refrigerant evaporators when refrigerant distribution was precisely controlled to produce a desired equal superheat in each circuit. This goal was accomplished by

The Pentagon Building Performance Report

January 1, 2003
Author(s)
P E. Mlakar, D O. Dusenberry, J R. Harris, G A. Haynes, Long Phan, M A. Sozen
Following the September 11 crash at the Pentagon of an airliner commandeered by terorists, the American Society of Civil Engineering established a building performance study team to examine the damaged structure and make recommendations for the future. The

The Virtual Cement and Concrete Testing Laboratory Version 3.0

January 1, 2003
Author(s)
Jeffrey W. Bullard
This NISTIR serves as the user's manual for Version 3.0 of the Virtual Cement and Concrete Testing Laboratory (VCCTL). Using the VCCTL, a user may create starting microstructures of cement (gypsum, fly ash, etc.) particles in water, hydrate the

Thermal and Flammability Properties of a Silica-Poly(methylmethacrylate) Nanocomposite

January 1, 2003
Author(s)
Takashi Kashiwagi, A B. Morgan, Joseph M. Antonucci, Mark R. VanLandingham, Richard H. Harris Jr., W H. Awad, John R. Shields
MMA, poly(metheylmethacrylate), nanocomposites were made by in situ radical polymerization of MMA, methylmethacrylate, with colloidal silica (ca. 12 nm) to study the effects of nanoscale silica particles on the physical properties and flammability

TROPODEGRADABLE AND OTHER ENVIRONMENTALLY ACCEPTABLE FLAME EXTINGUISHANTS

January 1, 2003
Author(s)
J D. Mather, R E. Tapscott
In work sponsored by the National Institute of Standards and Technology and the Next-Generation Fire Suppression Technology Program, our current research effort is directed toward the continued study of known promising as well as several new chemical

Estimating Temperatures in Compartment Fires

December 31, 2002
Author(s)
William D. Walton, Phillip H. Thomas
The ability to predict temperattures developed in compartment fires is of great significance to the fire protection professional. There are many uses for the knowledge of compartment fire temperatures, including the prediction of (1) the onset of hazardous
