The dynamics of the different flames are then addressed. First, the impact of hydrogen at atmospheric pressure is investigated. While the reference natural gas flame (1 bar, 0\% H2) presents a lifted M-shape with a strong Precessing Vortex Core (PVC), 40\% H2-enrichment modifies the flame which becomes an attached V-shape, with a weakened PVC and the triggering of a thermoacoustic oscillation at the system first acoustic mode. Second, the impact of mean pressure is analyzed by fixing the H2-enrichment while increasing the mean pressure to 3 and then 5 bar. As the pressure increases, the flame becomes more compact and the chemical as well as the turbulent time scales change, potentially affecting the flame/turbulence interaction. For these points, the thermoacoustic oscillation at the first system acoustic mode rapidly disappears and stable conditions are recovered.},
