DDES Study of Confined and Unconfined NACA Wing Sections Using Spectral Elements
Vishal Kumar, Ananias Tomboulides, Paul Fischer +1
We develop hybrid RANS-LES strategies within the spectral element code Nek5000 based on the class of turbulence models. We chose airfoil sections at small flight configurati…

Modeling Turbulence in the Atmospheric Boundary Layer with Spectral Element and Finite Volume Methods
Ananias Tomboulides Matthew Churchfield, Paul Fischer, Michael Sprague +1
We present large-eddy-simulation (LES) modeling approaches for the simulation of atmospheric boundary layer turbulence that are of direct relevance to wind energy production. In th…
