“…Global methods in modelling of radiation transfer in high temperature gases in nonisothermal, non-homogeneous media have proven to be the most computationally efficient methods for such predictions. These methods include the SLW (Spectral Line Weighted-sum-ofgray-gases) [1][2][3], ADF (Absorption Distribution Function) [4], FSK (Full Spectrum kdistribution) [5][6], and SLMB (Spectral Line Moment-Based) [7] methods. These methods can provide high accuracy of prediction of radiation transfer, often comparable to that of rigorous benchmark line-by-line (LBL) predictions but at significantly lower computational cost.…”

Following previous theoretical development based on the assumption of a rank correlated spectrum, the Rank Correlated Full Spectrum k-distribution (RC-FSK) method is proposed. The method proves advantageous in modeling radiation transfer in high temperature gases in non-uniform media in two important ways. First, and perhaps most importantly, the method requires no specification of a reference gas thermodynamic state. Second, the spectral construction of the RC-FSK model is simpler, requiring only two cumulative k-distributions. Further, although not exhaustive, example problems presented here suggest that the method may also yield improved accuracy relative to prior methods, and may exhibit less sensitivity to the blackbody source temperature used in the model predictions. This paper outlines the theoretical development of the RC-FSK method, comparing the spectral construction with prior correlated spectrum FSK method formulations. The work presents predictions using the new Rank Correlated FSK method and previous FSK methods in three different example problems. Lineby-line benchmark predictions are used to assess the accuracy.
