Sensing technologies and their application to detecting fires in buildings continue to evolve, and recent advances are summarized in this article. Work being...
An analytical model of the initial expansion of a fireball is presented.The model is based on an exact solution of the low Mach number combustion equations in...
The extinction and structure of non-premixed flames were investigated through the comparison of experiments and calculations using a counterflow configuration...
This year, the National Institute of Standards and Technology (NIST), formerly the National Bureau of Standards (NBS), turned 100 years old. During that century...
The events of September 11 have generated renewed interest in the use of protected elevators for egress and access. U.S. building codes contain requirements for...
This report compares results from similar egress models based on documented evacuation movement data. When EXIT89 and Simulex1 are used to 1) simulate the same...

Two gypsum wall assemblies were exposed to intense real-scale compartment fires, from the time of ignition to beyond flashover. The construction of each...
A dual burner apparatus has been developed for the purpose of assessing the flammability of a mattress/foundation combination in a manner that correlates with...
Simulation of the effects of severe fires on the structural integrity of builings requires a close coupling between the gas phase energy release andtransport...
There has been a great deal of recent experimental and, particularly, theoretical interest in the development of spatial and temporal oscillations in laminar...
The structural integrity of a building, and the safety of building occupants and first responders in an actual fire, will depend upon the quality of the...

This report presents the methodology for and results from a series of room-scale fire tests to produce data on the yields of toxic products in both pre...
The objective of fire hazard and risk analyses is to estimate conditions of safety for people, including those that are more sensitive to fire smoke than others...
A three-dimensional model of the probe volume in duel-beam interferometry measurements was developed to evaluate the effect of laser beam alignment errors...
Occupants in fire emergencies in buildings are presented with multiple pieces of information and environmental cues which produce varying levels of stress for...

This paper discusses three interrelated aspects of modeling scalar transport, mixing and combustion, in the context of large-eddy simulation (LES). In terms of...
At least three different physics based approaches to fire dynamics simulations have evolved over the years; lumped parameter or ''zone models'', computational...
A successful simulation of compartment fires using computational fluid dynamics (CFD) must be able to adequately model three significant phenomena: the...
