One of the major goals of fire research is to develop
the capability to make realistic assessments of fire
impact and risk by utilizing models. Currently the
large scale fire/plume models may not be validated and
hence calculations which may have a large
economic/safety impact may be considered suspect. As a
consequence, these models are under utilized. In order
to increase the level of confidence placed in these
computational models to an acceptable level a rigorous
experimental tomographic validation technique has been
under development at BFRL/NIST. In the pursuit, we have
analyzed data from both laboratory and computer
generated plumes in order to determine the number of
line-of-sight measurements, the detector topology, and
the temporal resolution needed to obtain accurate
tomographic reconstructions of the component
concentrations in asymmetric turbulent flow fields.
