AbstractThe wavelet features of rotating detonation waves (RDWs) are numerically investigated using Euler equations and a two-step induction-reaction model. The effects of the inflow stagnation temperature T-st and the heat release rate k(R) on the number, height and intensity of the RDWs are discussed in this study. An increase in the stagnation temperature results in more detonation waves in a combustion chamber, which indicates the number of RDWs is sensitivity to the thermodynamic state of the reactants. As the heat release rate decreases, the number of detonation wave decreases and an unstable wavelet pattern is observed. This is represented as the oscillation in height and intensity of the detonation. In addition, some numerical cases are performed to determine the effects of ignition patterns on the number of RDWs. The features of the flow fields are analyzed using varied inflow stagnation temperature and initiation patterns, identifying the co-existence of different wavelet configurations.
