|Title:||Distributed Detection for Tomographic Measurements of Component Concentrations in Fire Generated Plumes (NISTIR 5904)|
|Published:||October 01, 1996|
|Abstract:||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.|
