| Abstract | ||||
| The present work is a numerical simulation results from the modelling of a non-premixed methane fl ame with and without radiation models. CFD studies using FLUENT code were carried out for three cases; without radiation model, with the P-1 radiation model and with the discrete transfer radiation model. The model results from these three cases are compared with each other and with the experimental results. The discrete transfer and of the P-1 radiation models are assessed in a swirling methane non-premixed flame confined in an axisymmetric combustor. The predictions are involving the modeling of the combustion and radiation phenomena. Computational results with and without radiation effects are compared with experimental data and the two radiation models are evaluated in terms of computational efficiency, ease of application and predictive accuracy. The effects of momentum flux, swirl number and air inlet temperature on flame characteristics are examined. A comparison of realizable k- and standard k- turbulent models are presented. The results show the significant effect of studied parameters on the flame characteristics and temperature patterns.The results have demonstrated that the effect of thermal radiation is important even in flames, and that the discrete transfer and the P-1 radiation models and realizable k- turbulent model can be applied in industrial gas furnaces with relative ease, yielding accurate predictions. | ||||
