The Kinetic Model Including Singlet Oxygen and Ozone in Hydrogen-Air Mixture

Abstract:

To analysize the influence of singlet oxygen O₂(a¹Δ_g) and ozone O₃ on the hydrogen-air combustion system, a kinetic model must be defined. By simulating the ignition delay time, flame speed, flame temperature and the component changes of Starik model, GRI3.0 model, Konnov model and Mueller model using the software Chemkin4.1 and comparing the results with the experimental data, the Starik model is chosen as the basis of the study. Then singlet oxygen O₂(a¹Δ_g) and ozone O₃ is added in the basic model to form a new mechanism. The presence of singlet oxygen O₂(a¹Δ_g) and ozone O₃ is demonstrated to result in noticeable enhancement on flame propagation.
