This report describes the enhancements made to
Quintiere's flame spread model based on worked published
in the literature by other researchers. The height of
the ignition source flame, its extension under a
horizontal ceiling and the incident heat flux to a
target material have been addressed. The results from
the enhanced version of the model have been compared
with those obtained from an earlier version of the model
and with experimental data. The new version generally
shows an improvement over the previous versions although
there are isolated instances in which this is not the
case. This report also briefly describes a
user-friendly windows based front-end that has been
developed for the enhanced version of the model. The
interface can be used to read in existing model input
files, create new input files, execute the main QFSM
program and create simple on screen plots of the
results. The front-end also includes an online help
file that describes the various input parameters. A
single self-extracting file containing the QFSM model,
the interface, the help documentation and associated
support files has been created to simplify distribution
and installation of the software.
