摘要：
In this paper, in order to investigate the effect of working parameters on 3D non-premixed Flameless oxidation occurring in the IFRF furnace, large eddy simulation model is applied on OpenFOAM environment. The radiation and combustion are modeled by applying the finite volume discrete ordinate model and partially stirred reactor, respectively. Furthermore the detailed mechanism GRI-2.11 is undertaken represent chemistry reactions. The obtained results are compared with the published experimental measurements. After ensuring the accuracy of the LES method, the combustion characteristics are examined with different fuel injection angles, adding H2O, H-2, and the inlet Reynolds number. The results indicated significant changes in the characteristics of the Flameless oxidation process.
