Spectral radiation emitted by kerosene pool fires
Résumé
We present an equivalent medium model that considers emission from the ame volume to compute spectral radiation intensities. This is considered a more detailed description than common radiation models used in re safety applications, which often treat the ame as a grey emitting surface. Given its importance in re radiation, the present study focuses on emission by soot. The required parameters for the model are an equivalent absorption coecient, and an equivalent temperature. They were determined using two independent measurements, namely multispectral opacimetry, and infrared spectrometry. Results are presented for kerosene pool res (widths from 30 cm to 250 cm). It is shown that the equivalent temperature can be considered independent of ame size, and thus an intrinsic parameter of the fuel. These results also make clear that radiation emitted from the ame is not grey, and can only be considered black for very large ames (i.e. wider than 1.75 m for present tests).
