Transient Measurements of Gas Species Concentrations and Soot Properties in Pool Fires

Researchers at Sandia National Laboratories have been investigating large-scale pool fires, both experimentally and numerically, for several years, because of the risk that these fires pose to critical engineered systems during transport accident scenarios [1]. In addition, Sandia recently implemented an insulated, water-cooled fiber optic probe that used a combined HeNe-laser-absorption, 2-color emission technique to determine soot volume fraction distributions and soot temperatures over a 2-cm sampling distance within 5-m diameter JP-8 pool fires [2].
