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.
