Technical review of radiative-property modeling approaches for gray and nongray radiation, and a recommended optimized WSGGM for CO2/H2O-enriched gases
Published 2025-03-01“…Precise modeling of the spectral behavior of radiatively-active gases through detailed approaches, such as the line-by-line (LBL) approach or the statistical narrow band (SNB) approach is computationally formidable, and thus simplified techniques are sought as practical alternatives for numerical modeling through computational fluid dynamics (CFD) solvers. In the current study, we consider the weighted-sum-of-gray-gases model (WSGGM) as a desired simplified approach to estimate the radiative properties needed for radiation calculation when numerically simulating oxy-fuel combustion as well as other processes involving high temperatures with high concentrations of CO2 and/or H2O. …”
