This document is an instructional manual which will
facilitate use of the computer program FIRST. (The name
"FIRST" is an acronym; it stands for FIRe Simulation
Technique). This is a prototype of a "benchmark"
computer model of how a fire develops in a single
compartment. Given a fire (or fires) ignited on one or
more fuel sources, FIRST describes the principal
phenomena which occur, such as the movement of gases in
and out of the compartment, the growth of the fire(s),
the development of a hot layer, etc. This guide is not
meant to be documentation for the model, and so detailed
descriptions of the physics or of the program structure
have been kept to a detailed descriptions of the physics
or of the program structure ave been kept to a minimum.
The principal emphasis has been on how to input the
information needed to run the program, and on the output
obtained. Only a dozen pages of instructions are needed
for the input, but an extensive section has been
included which gives "worked examples" of the use of the
program. There is also a section which gives
suggestions for using it to simulate fires and situation
for which no explicit provision has been made. Finally,
a short table of thermophysical data appropriate for
running the program has been included.
