The present work presents a Zonal Detached Eddy Simulation (ZDES) to simulate a spatially
developing turbulent boundary layer over a smooth flat plate at Re θ= 2900. Results are
compared with the experimental data of De Graaff and Eaton [1]. A synthetic reconstruction
method for the pseudo-viscosity field ν˜ is proposed in the frame of a synthetic eddy method.
First, it is shown that ZDES amounts to LES with a plausible one-equation subgrid scale
model and wall modeling. More precisely, both the mean and second-order field are well …

A Wall-Modeled Large Eddy Simulation (WMLES) of a spatially developing zero-pressure
gradient smooth flat plate turbulent boundary layer is performed by means of the third mode
of the Zonal Detached Eddy Simulation technique. The outer layer is resolved by a Large
Eddy Simulation whereas the wall is modeled by a RANS simulation zone, with a RANS/LES
interface prescribed at a fixed location. A revisited cost assessment of the Direct Numerical
Simulation of high Reynolds numbers (Re θ⩾ 10 000) wall-bounded flows emphasizes how …
