Axial profiles of the normalised Favre-averaged temperature and mass fractions of H, O, OH, and HO₂ obtained at the radial locations of stabilisation corresponding to each 𝑇_𝑐: (a) Girimaji’s model and (b) Mortensen’s model. The vertical dash-dotted and dashed lines correspond to the axial locations of maximum HO₂ and liftoff height, respectively. The circles indicate the locations of the maximum slopes.
