We use infrared imaging and laser diagnostics to measure surface and gaseous temperature and species concentration from small scale (10cmx10cm), radiatively heated pine samples during pyrolysis and ignition. These results are used to validate reduced order chemical kinetic and computational fluid dynamic models, developed in parallel with experimental investigations.
