Understanding combustion noise generation is crucial to implement noise reduction strategies in aircraft propulsion systems. Noise generation is here investigated in hydrogen and methane-hydrogen laminar flames, stabilized over a bluff-body burner. Numerical simulations are performed adopting detailed reaction schemes and a fully resolved approach and compared with experimental recordings.
