The evaporation of sprinkler droplets is an important phenomena in fire simulations both for heat removal from the gas and for heat removal from surfaces. In this paper, we address the problems of potential numerical instability and super-saturation that

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
Smokeview is a software tool designed to visualize numerical calculations generated by the NIST Fire Dynamics Simulator (FDS), a computational fluid dynamics (CFD) model of fire-driven fluid flow. For details on setting up and running FDS cases read the
A series of measurements were made to characterize the global properties of moderate-sized pool fires steadily burning in a quiescent environment. A wide range of parameters were considered including lightly and heavily sooting hydrocarbon fuels (methane
A series of measurements was made to characterize the structure of a moderate-sized methanol pool fire steadily burning in a quiescent environment. Time averaged local measurements of temperature and gas species concentrations were made in a steadily
A probabilistic methodology is presented for estimating the building fire losses. This methodology is applied to the specific case of residential upholstered furniture (RUF) fires. The objective of this application is to assess the fire losses associated

Thermodynamic equilibrium calculations, as well as perfectly-stirred reactor (PSR) simulations with detailed reaction kinetics, are performed for a potential halon replacement, C3H2F3Br (2-BTP, C3H2F3Br, 2-Bromo-3,3,3-trifluoropropene), to understand the

CFAST is a two-zone fire model capable of predicting the environment in a multi-compartment structure subjected to a fire. It calculates the time evolving distribution of smoke and fire gases and the temperature throughout a building during a user-

This supplement to the CFAST Technical Reference Guide provides details of the software development process for CFAST and accompanying experimental evaluation of the model. It is based in part on the Standard Guide for Evaluating the Predictive Capability
The purpose of this document is to describe the policies and procedures for developing and maintaining CFAST. Such a document is commonly referred to as a {\em Configuration Management Plan}. Description of the theoretical basis of the model, instructions

A strategy is proposed to guarantee realizability of species mass fractions in explicit time integration of the partial differential equations governing fire dynamics, which is multi-component transport problem. For a mixture of $n$ species, the
The NRC has established requirements that are the design bases for packaging and transportation of spent nuclear fuel assemblies under normal conditions of transport (NCT) and for hypothetical accident conditions (HAC). Real-world accidents of greater
