Study of active particles' influences on combustion of H₂/Air mixture

The chemical kinetic model of H₂/Air mixture combustion was established in this article.With the non-equilibrium plasma,this paper calculated and analyzed how the active particle(O,H) and radical(OH) produced by gas discharge influenced the components in the combustion,the temperatures and pressures at different equivalent ratios.Therefore,this paper can provide a theoretical foundation for the experimental research and practical application of plasma assisted combustion(PAC) in the aero-engine combustion chamber.The results show that PAC can improve reaction efficiency,combustion temperature and flame spread velocity,reduce the rise-time of combustion and strongly influence H₂/Air mixture combustion.
