Recently, version 2 of the NIST Fire Dynamics Simulator
(FDS v2) was released. A number of major changes were
made to version 1 including new combustion and radiation
sub-models. These features were added to improve the
simulations of flashover, but they require validation
against experimental data. The Virginia Tech (VT) Fire
Research Laboratory is currently undertaking a study of
compartment fires3 using a half-scale ISO 9705
compartment. Fires studied in this compartment span a
wide range of heat release rates, thus providing an
excellent set of data with which to validate the new
sub-models. FDS v2 was used to simulate 8 tests in the
VT compartment. Comparisons to experimental data were
made. The comparisons indicate the new submodels perform
well for flashed over compartments. Major species, mass
flows, and temperatures are all reasonably predicted.
However, predictions of minor species and mass flow
rates for well-ventilated tests indicate that further
refinement of the new submodels is needed.
