4. Conclusions
- (1)
- The pressure in the strut-based scramjet combustor shows significant oscillation characteristics when the air parameters at the combustor inlet and the fuel parameters at the injector outlet are under certain conditions, and these pressure oscillation situations correspond to supersonic combustion instability.
- (2)
- The pressure oscillations of the sampling points analyzed using FFT have broadband and two dominant frequency ranges. One dominant frequency range is below 20,000 Hz while the other is around 50,000 Hz.
- (3)
- The pressure oscillations of the whole combustor analyzed using DMD have multiple dominant frequencies, including relatively low frequency of 2984 Hz, high frequency of 62,180 Hz, and very high frequency of 110,562 Hz.
- (4)
- Large pressure oscillations in the strut-based scramjet combustor supersonic combustion instability are closely related to wake instability, shear layer instability, shear layer and wave interactions, and combustion.
- (5)
- Reducing the air total temperature at the combustor inlet can attenuate the pressure oscillations in supersonic combustion instability, and reducing the fuel flow rate at the injector outlet can also attenuate the pressure oscillations in supersonic combustion instability.
