“…We can now apply the elementwise SGWT scale-separation operation to the three-scale VMS-LES approach of Section 2.2. By summing up Equations (20) and (21) and using the all-all approach for the subgrid stress tensor (Table 1), we have…”

“…This approach was demonstrated by Ramakrishnan and Collis on a turbulent channel flow test case. Modal FEM, in conjunction with three‐scale VMS and the constant‐coefficient Smagorinsky model was tested out for a circular cylinder test case and on the 3D Taylor‐Green vortex (3D‐TGV) . Furthermore, tests using the three‐scale VMS procedure in the framework of mixed finite‐element/finite‐volume methods were carried out, for flows around bluff bodies, in the work of Munts et al and Moussaed et al Finally, we must point out the attempt by Wasberg et al, which utilized a nodal continuous Galerkin (CG) discretization with the Legendre polynomials for the purpose of scale separation for VMS‐LES upon the incompressible channel flow.…”

“…In [34], Chapelier et al have proposed a variational multiscale approach based on a modal DG method and applied it to the Taylor-Green vortex configuration at Re = 3 000. Finally, Beck et al [35] have studied the influence of over-integration on the performance of subgridscale models. The authors demonstrate the benefits of using de-aliasing when a subgrid-scale closure is used at high polynomial degrees.…”

“…They thus fundamentally differ from the original VMS idea, that is, the decomposition of the true solution into a discontinuous coarse-scale function space and an accompanying discontinuous fine-scale function space. While several authors have investigated the enhancement of DG methods with fine-scale eddy viscosity or wall models, [25][26][27][28][29][30][31] DG methods based on a residual-based VMS subgrid-scale model are still largely unexplored. To some extent, this may be attributed to the importance of coarse-scale continuity in the derivation of the VMS method.…”
