| description | Rotating detonation has the potential to enhance the performance of turbine engines significantly. The detonation products generated by rotating detonation waves (RDWs) produce extreme temperatures. To mitigate thermal erosion of the RDC casing, a jet-cooling structure serves as an effective thermal protection mechanism. This paper combines numerical simulations and experiments to investigate the operating characteristics of a combustor within rotating detonation turbine engine (RDTE) equipped with a jet-cooling structure. Utilizing H2 as fuel, air is split at the inlet, one part enters the jet-cooling channel while the other part acts as an oxidizer entering the RDC. The study results show that mixing uniformity between air and H2 along the axial direction of the RDC generally indicates an upward trend. Four modes were obtained in the experiments: sawtooth wave, double-wave collision, single wave, and double wave. Among these, the single-wave mode exhibited the highest pressure-wave amplitude; furthermore, both the pressure and velocity of the RDW increased with rising equivalence ratio (ER) values. The results demonstrated that the jet-cooling structure can significantly reduce the gas temperature before entering the turbine, thereby verifying the feasibility of the RDTE with the jet-cooling structure. |
