This work used simultaneous MHz-rate hydroxyl planar laser-induced fluorescence (OH PLIF) and chemiluminescence to reveal the detailed detonation wave structure in an H2-air non-premixed rotation detonation engine (RDE). These data were used for detailed analysis of the effects of reactant stratification with the help of unsteady Reynolds averaged Navier-Stokes (URANS) simulations of the full RDE geometry.
