“…This has resulted in the so-called full-spectrum correlated k-distribution (FSCK) method. Over the past two decades, significant research has gone into extending the FSK method to nonhomogeneous media with and without soot, and liquid fuels [137][138][139][140][141][142][143], nongray walls [144,145], and k-distribution databases constructed from LBL and narrow-band data have been created and disseminated [146,147]. Today, in its third edition, the FSK model is one of the most accurate, efficient, and popular models for the computation of nongray radiation in combustion environments [148][149][150].…”

Modeling thermal radiation in combustion environments can be extremely challenging for two main reasons. First, the radiative transfer equation (RTE), which is the cornerstone of modeling radiation in such environments, is a five-dimensional integro-differential equation. Second, the absorption and scattering coefficients of molecular gases and particulates prevalent in combustion environments oscillate strongly with the wavenumber (or wavelength), i.e., the medium is strongly nongray, requiring the solution of the RTE for a large number of wavenumbers. This article reviews the progress that has been made in this area to date with an emphasis on the work performed over the past three decades. Progress in both deterministic and stochastic (Monte Carlo) solutions of the RTE is reviewed, in addition to the review of the treatment of the spectral properties of gases, soot, and fuel droplets that dominate combustion environments, i.e., spectral or nongray models. The application of the various state-of-the-art nongray models and RTE solution methods to flames (particularly turbulent), fires, combustors, and other combustion systems are summarized along with a critical discussion of the pros and cons of the models and methods. Finally, the challenges that remain in modeling thermal radiation in combustion systems are highlighted and future outlooks are shared.

“…Values of MR set to 1.5 and 3.0 were considered in [27] and [28], respectively. A large range of MR has been studied in [29][30][31][32][33]. To give a comprehensive and detailed study, our methodology is applied to CO 2 -H 2 O mixtures with MR set to 2.0, which are representative to products of typical air-fired methane combustion.…”
