- •
Model scramjet combustors with parallel and tandem dual-cavity are studied.
- •
Flame luminosity, schlieren, and OH spontaneous emission imaging were implemented.
- •
Simulation performs good qualitative and quantitative agreement with experiment.
- •
Coexistence of three key parts is concluded for flame stabilization in dual-cavity.
