ABSTRACT

The previously published mathematical correlations of the absorption-line blackbody distribution function, central to the spectral-line based weighted-sum-of-gray-gases model (SLW), have been extended to elevated pressures by introducing a dependence on an effective broadening pressure. Comparisons between experimentally determined total emissivities and those calculated with the model show good agreement. Good agreement at elevated pressure between line-by-line benchmarks, and model predictions is also demonstrated.
