Abstract: This paper conducted preliminary numerical simulation of their interactions by means of CFD method.The stoichiometric hydrogen-air mixture was employed as reactants and 1-step finite rate reaction model was used to investigate the interaction of detonation wave with a stationary blade.The simulation results indicate that the detonation wave attenuates after passing the blade passage,and generates a strong compression wave reflecting back upstream from leading edge of blade at the same time,This mitigates the pulse effect on turbine blade and causes a short period of back mass flow at turbine inlet surface.A high pressure environment is formed at the leading edge,The pressure time sequences at pulse detonation engine(PDE) exit surface shows many pairs double-peaks are gradually attenuated.
