An Update Guide for HAZARD I Version 1.2

May 1, 1994
Author(s)
Richard D. Peacock, Walter W. Jones, Glenn P. Forney, Paul A. Reneke, Richard W. Bukowski, J H. Klote
A method for quantifying the hazards to occupants of buildings from fires, and the relative contribution of specific products (e.g., furniture, wire insulation) to those hazards is presented. This method,called HAZARD I, combines expert judgment and

Human Exposure and Environmental Impact

April 1, 1994
Author(s)
E Braun, Richard D. Peacock, Glenn P. Forney, George W. Mulholland, Barbara C. Levin
Although these agents are typically employed in unoccupied sections of an aircraft, the possibility of human exposure still exists during handling, storage, and transport. Thus, it is important to know if the accidental release of the 12 agents in areas of

Analyzing and Exploiting Numerical Characteristics of Zone Fire Models

January 1, 1994
Author(s)
Glenn P. Forney, W F. Moss
In order to design robust and stable zone fire modeling algorithms, the numerical properties of computer arithmetic and modeling differential equations must be understood. This report examines some of these properties and provides tools for their analysis

Pressure Equations in Zone-Fire Modeling

January 1, 1994
Author(s)
Ronald G. Rehm, Glenn P. Forney
The nonadiabatic nature of low-speed combustion and fire, in which strongly exothermic reactions produce large temperature variations but only mild pressure variations, can cause difficulty when integrating zone models of enclosure fires. Examples of

CFAST: The Consolidated Model of Fire Growth and Smoke Transport.

February 1, 1993
Author(s)
Richard D. Peacock, Glenn P. Forney, Paul A. Reneke, Walter W. Jones, R W. Portier
CFAST is a zone 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-specified fire

CFAST, the Consolidated Model for Fire Growth and Smoke Transport

January 7, 1993
Author(s)
Richard D. Peacock, Glenn P. Forney, Paul A. Reneke, Walter W. Jones
CFAST is a zone 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-specified fire

Improvement in Predicting Smoke Movement in Compartmented Structures

January 1, 1993
Author(s)
Walter W. Jones, Glenn P. Forney
This paper describes improvements which have been made in the CFAST model of fire growth and smoke transport for compartmented structures. In particular, we are interested in the ability to model the movement of toxic gases from the room of origin of a

Note on the Pressure Equations Used in Zone Fire Modeling (NISTIR 4906)

August 1, 1992
Author(s)
Ronald G. Rehm, Glenn P. Forney
Examples of simple zone fire models are analyzed. These models illustrate the nature of the numerical problems commonly encountered in zone models of enclosure fires. Often these difficulties arise in the solution of the equations for the pressure in

Implicitly Coupling Heat Conduction Into a Zone Fire Model (NISTIR 4886)

July 1, 1992
Author(s)
W F. Moss, Glenn P. Forney
This report examines several methods for coupling the partial differential equations that arise in conductive heat transfer with the ordinary differential equations that arise in zone fire modeling. Two existing algorithms (method of lines and time

Modeling Smoke Movement Through Compartmented Structures (NISTIR 4872)

July 1, 1992
Author(s)
Walter W. Jones, Glenn P. Forney
This paper describes a model of fire growth and smoke transport for compartmented structures, with emphasis on those aspects which are important to making correct predicitons of smoke movement in multicompartment structures. In particular, we are

Computing Radiative Heat Transfer Occurring in a Zone Fire Model

November 1, 1991
Author(s)
Glenn P. Forney
Radiation, convection and conduction are the three mechanisms which a zone fire model must consider when calculating the heat transfer between fires, wall surfaces and room gases. Radiation dominates the other two modes of heat transfer in rooms where
