Modern discontinuous Galerkin methods for the simulation of transitional and turbulent flows in biomedical engineering: A comprehensive LES study of the FDA benchmark nozzle model
Niklas Fehn, Wolfgang A. Wall, Martin Kronbichler
This work uses high-order discontinuous Galerkin discretization techniques as a generic, parameter-free, and reliable tool to accurately predict transitional and turbulent flows th…
A matrix-free high-order discontinuous Galerkin compressible Navier-Stokes solver: A performance comparison of compressible and incompressible formulations for turbulent incompressible flows
Niklas Fehn, Wolfgang A. Wall, Martin Kronbichler
Both compressible and incompressible Navier-Stokes solvers can be used and are used to solve incompressible turbulent flow problems. In the compressible case, the Mach number is th…
Efficient Explicit Time Stepping of High Order Discontinuous Galerkin Schemes for Waves
Svenja Schoeder, Katharina Kormann, Wolfgang Wall +1
This work presents algorithms for the efficient implementation of discontinuous Galerkin methods with explicit time stepping for acoustic wave propagation on unstructured meshes of…
Effective slip over partially filled microcavities and its possible failure
Zhouyang Ge, Hanna Holmgren, Martin Kronbichler +2
Motivated by the emerging applications of liquid-infused surfaces (LIS), we study the drag reduction and robustness of transverse flows over two-dimensional microcavities partially…
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…
Robust and efficient discontinuous Galerkin methods for under-resolved turbulent incompressible flows
Niklas Fehn, Wolfgang A Wall, Martin Kronbichler
We present a robust and accurate discretization approach for incompressible turbulent flows based on high-order discontinuous Galerkin methods. The DG discretization of the incompr…
