REDUCTION OF NO FORMATION BY THERMAL EFFECT OF A TURBULNENT DIFFUSION FLAME H2/AIR MODELED BY THE CONCEPT OF LAMINAR FLAMELET

Highly exothermic reactions are responsible for the formation of harmful polluting chemical species to humans and the biosphere. In this context, nitrogen oxides (NOx) are pollutants that are the subject of special attention on the part of regulators. In this work we studied the impact of a co-flow...

Summary:Highly exothermic reactions are responsible for the formation of harmful polluting chemical species to humans and the biosphere. In this context, nitrogen oxides (NOx) are pollutants that are the subject of special attention on the part of regulators. In this work we studied the impact of a co-flow swirl on the internal structure of a turbulent diffusion flame H2-N2/Air and its role in reducing the formation of NO, which is modeled by the concept of laminar flamelet, while the flow field is modeled by the standard model k-ε, with a correction term for round jets.The results show good agreement with data from the experimental data.
