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
