What is Computation of Turbulent Reactive Flows in Industrial Burners about?
This paper presents models that are suitable for computing steady and unsteady gaseous combustion with ®nite rate chemistry. Reynold averaging and large eddy simulation (LES) techniques are used to model turbulence for the steady and unsteady cases, respectively. In LES, the Reynold stress terms are modelled by a linear combination of the scalesimilarity and eddy dissipation models while the cross terms are of the scale-similarity type. In Reynold averaging, the conventional k± two-equation model is used. For the chemical reactions, a 3-step mechanism is used for methane oxidation and the extended Zeldovich and N 2 O mechanism are used for NO formation. The combustion model is a hybrid model of the Arrhenius type and a modi®ed eddy dissipation model to take into account the eects of reaction rate, ̄ame stretch and turbulent intensity and scale. Numerical simulations of a ̄at pulse burner and a swirling burner are discussed.
