| Summary: | This study investigated the structural evolution of cone-induced oblique detonation waves using a three-dimensional multicomponent compressible flow framework. Through coupled Euler/Navier-Stokes equations with finite-rate chemistry, distinct Mach number-dependent transition mechanisms were identified: at Ma=3.5, continuous compression establishes a smooth shock-to-detonation transition, whereas Ma=2.9 exhibits abrupt transition characteristics. The interaction between three-dimensional curvature effects and cellular detonation structures generates intensified temperature gradients. The viscous effects reduce the detonation initiation zone length through thermal conduction, while the boundary layer recirculation zone accelerates localized chemical reactions to trigger detonation. Meanwhile, momentum diffusion suppresses the growth of initial perturbations, thereby delaying the wave front instability. The study shows a synergistic regulation mechanism between three-dimensional curvature and viscous effects, providing fundamental insights for the geometric parameter design and flow stability control of oblique detonation combustors. |
