Dembele, S., Zhang, J. and Wen, J.X., 2003. Evaluation Of The Correlated-K And Other Gas Radiation Models For Combustion Applications. Fire Safety Science 7: 927-938. doi:10.3801/IAFSS.FSS.7-927
ABSTRACT
The correlated-k (CK) distribution gas model is evaluated for some typical fires and combustion applications. The method based on the cumulative distribution function of the absorption coefficient has been widely used for atmospheric applications, but little tested for combustion systems. The CK approach, suitable for mixtures of gases and scattering particles is applied in the current work to PMMA and natural gas fires. For comparison purposes, results obtained with the narrow band statistical (NBS) and weighted sum of gray gases (WSGG) models are also presented for the same scenarios. The results clearly show that the CK approach provides a good level of accuracy with acceptable CPU times for the fire configurations tested, in the prediction of radiative quantities.
