A Discontinuous Galerkin Variational Multiscale Approach to LES of Turbulent Flows
In recent work (Chapelier et al, Comput Method Appl Mech Eng 307:275–299, 2016),  we have developed a variational multiscale simulation (VMS) approach based on a modal discontinuous Galerkin (DG) method. The separation of scales is achieved in each element via projection onto the discontinuous modal space. In (Chapelier et al, Comput Method Appl Mech Eng 307:275–299, 2016), , the DG-VMS technique was applied to the Taylor–Green vortex (TGV) flow at \(Re=3\,000\) demonstrating the potential of this approach to perform LES.
