A computational fluid dynamics study of turbulence, radiation, and combustion models for natural gas combustion burner

This paper presents a Computational Fluid Dynamics (CFD) study of a natural gas combustion burner focusing on the effect of combustion, thermal radiation and turbulence models on the temperature and chemical species con-centration fields. The combustion was modelled using the finite rate/eddy dissip...
