Simultaneous Optical Measurement of Soot Volume Fraction, Temperature and CO2 in Heptane Pool Fire
M Y. Choi, Anthony Hamins, H. Rushmeier, Takashi Kashiwagi
Detailed measurements of the temperature, soot volume fraction and CO2 have been performed for a 10 cm diameter heptane fire. In addition, the concentrations of H2O and CO were inferred from generalized state relationships. The heat feedback to the surface was calculated by using a reverse Monte-Carlo method in conjunction with RADCAL. The calculated heat fluxes to the surface with and without gas emission indicate that the contributions from the gaseous combustion products to total radiation are significant for heptane due to its mildly sooting nature. Simultaneous optical measurements using two probes were used to investigate the importance of temporal correlations on the heat transfer calculations. Measurements made throughout the fire incident that non-simultaneous data sets can be used to accurately predict the heat transfer to the surface.
