- •
Mixing and combustion properties in a dual-mode combustor were explored numerically.
- •
Influences of injection strategy and fuel equivalence ratio on mode transition were evaluated.
- •
Vertical injection is beneficial for mode transition with fixed total equivalence ratio, as well as larger total equivalence ratio.
- •
Lower total equivalence ratio and smaller fuel equivalence ratio discrepancy are beneficial for mixing augmentation.
