| Summary: | Based on the Navier–Stokes equation with chemical reaction kinetics, rotating detonation waves are numerically simulated using premixed reactants H2/air at a stoichiometric ratio. The triple-point structure on the detonation front is captured. The self-sustained combustion process in rotating detonation waves is analyzed. Through innovatively utilizing the cell structure, the essential moments of the generation and propagation of new triple-point structures at the unbounded side of the rotating detonation front are discriminated successfully. The generation model of the new triple-point structure is proposed. The new model helps deeply understand the essence of self-sustained combustion in rotating detonation waves, which may serve as guidance in the engineering design of the rotating detonation engines. |
