- •
Mode transition mechanism in a strut-based dual mode combustor was investigated.
- •
Inlet boundary conditions, injection strategy and pressure ratio effects were evaluated.
- •
Low freestream Mach number is beneficial for the ramjet mode operation.
- •
Jet-to-crossflow pressure ratio is the greatest factor for the mode transition.
