    "abstract": "One of the more promising recent approaches to turbulence modelling is the\nVariational Multiscale Large Eddy Simulation (VMS LES) method proposed by\nHughes et al. [Comp. Visual. Sci., vol. 3, pp. 47-59, 2000]. This method avoids\nseveral conceptual issues of traditional filter-based LES by employing a priori\nscale partitioning in the discretization of the Navier-Stokes equations.\n  Most applications of VMS LES reported to date have been based on hierarchical\nbases, in particular global spectral methods, in which scale partitioning is\nstraightforward. In the present work we describe the implementation of the\nmethodology in a three-dimensional high-order spectral element method with a\nnodal basis. We report results from coarse grid simulations of turbulent\nchannel flow at different Reynolds numbers to assess the performance of the\nmodel.\n  Key words: Large eddy simulation, variational multiscale method, spectral\nelement method, incompressible flow 1991 MSC: 76F65, 65M60, 65M70 PACS:\n47.27.Eq, 02.70.Hm, 02.70.Dh",
