Abstract: Plasma assisted combustion process is a non-equilibrium,non-uniform and transient physical chemistry process. Active particle is a key problem in the calculation of plasma assisted combustion. The combustion chemical kinetic model of H2/Air is established. The non-equilibrium plasma conditions which the active particle(O,H) and (OH) produced by gas discharge influence the components, temperature and pressure in the combustion process under different initial temperature were calculated and analysed. It provides theoretical base for the experiment and application of plasma assisted combustion in aircraft engine combustion chamber. The results show that plasma assisted combustion can improve reaction efficiency, reduce combustion rise time, increase combustion temperature and flame propagation velocity and strongly influence H2/Air mixture combustion.
