“…To support inhomogeneous media, the FSK method is extended and different modified versions such as fullspectrum correlated-k distribution method (FSCK) have been developed. This method assumes that the spectral absorption coefficient of a participating medium at a local thermal state can be correlated with the absorption spectrum of a reference state [15]. The accuracy of this method therefore depends on the validity of this assumption; however, it allows modeling of various combustion domains without having the detailed values of the absorption coefficient at different thermal states [16,17].…”
