This work presents a numerical study of radiation heat transfer and its interaction with gray and spectral radiation of combustion products and soot that are formed in a turbulent non-premixed combustion process. To this purpose, WSGGM, Rayleigh, Narrow-Band Model and semi-empirical radiation properties models are considered. Two situations are studied, 1-D radiation problem and non-premixed gaseous combustion process. The results demonstrate that models exhibit discrepancies that are smaller than available line-by-line or experimental data. A study of the factors which influences such a disagreement is presented, underscoring the role of chemical kinetics of hydrocarbon species and of soot oxidation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
