- •
As the global equivalence ratio increases, the combustion oscillation becomes more regular and frequent.
- •
The combustion oscillation is the most intensive in the vicinity of the fuel jet.
- •
The combustion oscillation is more possible when the cavity is mounted on the expansion-side wall.
- •
The distributed injection scheme is effective to avoid the combustion oscillation in scramjet combustor.
- •
The varying fuel has a significant effect on the reaction process in scramjet combustor.
