Efficiency of high-performance discontinuous Galerkin spectral element methods for under-resolved turbulent incompressible flows
Niklas Fehn, Wolfgang A. Wall, Martin Kronbichler
The present paper addresses the numerical solution of turbulent flows with high-order discontinuous Galerkin methods for discretizing the incompressible Navier-Stokes equations. Th…

Wall modeling via function enrichment within a high-order DG method for RANS simulations of incompressible flow
Benjamin Krank, Martin Kronbichler, Wolfgang A. Wall
We present a novel approach to wall modeling for RANS within the discontinuous Galerkin method. Wall functions are not used to prescribe boundary conditions as usual but they are b…
