Hybrid RANS/LES Simulation of Turbulent Combustion in a SCRAMJET Combustor using Flamelet Progress Variable Method

摘要

The Zonal Hybrid RANS/LES approach is used tornsimulate the scramjet combustion with strong shockrninteraction. As a combustion model, the flameletrnprogress variable (FPV) method is implemented torncapture physical phenomena such as lifted-flame. Byrncomparing with steady laminar flamelet method results,rnit can be seen that the FPV method is able to predict thernlifted flame dynamics.
