Deciphering boundary layer dynamics in high-Rayleigh-number convection using 3360 GPUs and a high-scaling in-situ workflow
Mathis Bode, Damian Alvarez, Paul Fischer +10
Turbulent heat and momentum transfer processes due to thermal convection cover many scales and are of great importance for several natural and technical flows. One consequence is t…
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…
Spectral Element Simulation of Liquid Metal Magnetohydrodynamics
Yichen Guo, Paul Fischer, Misun Min
A spectral-element-based formulation of incompressible MHD is presented in the context of the open-source fluid-thermal code, Nek5000/RS. The formulation supports magnetic fields i…
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…
