Original abstract
The present paper presents an application of computational fluid dynamics (CFD) to simulating an industrial-scale low NOx burner. The main aim of the performed research is to provide the experimentally validated computational prediction of turbulent, non-premixed swirling gas flame in an air-staged burner. Computations are performed using the k-?, k-? and Reynolds-stress turbulence models in order to examine the relative performances of these moment closure models. The predictions are validated using measured values of local wall heat fluxes and flue gas temperature collected during a long-time experiment at an advanced burner-testing facility. The results show that all turbulence models overpredict the wall heat fluxes on average 10%.
