Numerical simulation of detonation wave interacting with turbine blade

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.
