摘要	Based on the dynamic zone flamelet model (DZFM), the turbulent combustion of the DLR supersonic combustor with a wedge-shaped flame holder is numerically studied by IDDES. The mixing-relevant flow structures, combustion characteristics, and reaction paths were analyzed. The significant variation of flame modes, turbulencechemistry interaction modes, and correlations between species (YOH) and mixture fraction suggests that applying a single flamelet for the whole physical space may introduce remarkable errors in describing the reacting states. Dynamically partitioning the flow field based on multiple zone division indices can effectively reduce conditional fluctuations and make the first-order closure assumption more valid. The results also demonstrate the necessity of a low-Re modification to DZFM, even for supersonic combustion.
