Abstract Well-resolved Large-Eddy Simulations (LES) of a pseudo-shock system in the
divergent part of a Laval nozzle with rectangular cross section are conducted and compared
with experimental results. The LES matches the parameter set of a reference experiment.
Details of the experiment, such as planar side walls, are taken into account, all wall
boundary layers are well-resolved and no wall model is used. The Adaptive Local
Deconvolution Method (ALDM) with shock sensor is employed for subgrid-scale turbulence …
