Abstract
Simulations of compressible boundary layer flow at three different Reynolds numbers (Reδ = 5.59×104, 1.78×105, and 1.58×106) are performed using a hybrid large-eddy/Reynolds- averaged Navier-Stokes method. Variations in the recycling/rescaling method, the higher-order extension, the choice of primitive variables, the RANS/LES transition parameters, and the mesh resolution are considered in order to assess the model. The results indicate that the present model can provide good predictions of the mean flow properties and second-moment statistics of the boundary layers considered. Normalized Reynolds stresses in the outer layer are found to be independent of Reynolds number, similar to incompressible turbulent boundary layers.
