| 英文摘要 | A numerical simulation solving the Reynolds-averaged Navier-Stokes equation is presented to investigate the initiation and evolution of the wedge-induced oblique detonation wave (ODW) with emphasis on the effects of the burning boundary layer. The nondimensional activation energy (E-a) is selected as the bifurcate parameter, which varies from 30 to 50. The largest induction ignition length behind the oblique shock/detonation wave is shown to be proportional to the E-a. The initiation of ODW can be attributed to the collision and diffraction of reactive waves. The wave configuration, a series of compression waves (or shock wave), is observed at the conjunction point of the burning boundary layer and combustion wave, which intensifies the pressure jump as increasing the E-a. The polar line analysis demonstrates that the pressure jump triggers the transition from regular reflection to Mach reflection near triple-point. The oscillations of the ODW wave structures, for example, the triple-point and Mach stem, can be attributed to the Rayleigh-Taylor instabilities developed on the reaction front of the boundary layer, which shall be appropriately suppressed to remain the steadiness of the ODW and flow configuration.
