In this paper an experimental study is presented of the influence of an externally applied thermal radiant flux on the evaporation, or burning rate of a 15-cm-diameter kerosene pool fire, and on the structure of the buoyant flame developed over the liquid fuel surface. The results show that the burning rate increases with the external radiation, but as the radiant flux increases its influence is reduced. This seems to be due primarily to the related increase in the flame volume and opacity that attenuate the radiation that actually reaches the liquid surface. Detailed measurements of the temperature, CO{sub 2}, CO, and O{sub 2} concentrations, and monochromatic absorption coefficient-or equivalently soot-provide information about the flame structure and its dependence on the applied radiant flux. Increasing the radiant flux causes an increase in the flame volume and consequently a widening of the spatial distribution of the flame structure, although the overall flame characteristics and maximum temperatures and concentration levels remain unchanged.
