Rotating-disk turbulent boundary layer
The following are two visualizations from direct numerical simulations (DNS) of the rotating-disk (von Kármán) three-dimensional turbulent boundary layer, performed using Neko
APS Gallery of Fluid Motion 2026 submission for an extreme-scale DNS of the rotating-disk turbulent boundary layer up to $Re_\tau = 2300$ with 52 million spectral elements (18 billion grid points), performed using 3072 GH200 superchips on JUPITER
DNS of the rotating-disk turbulent boundary layer with 3.75 million spectral elements, performed on LUMI
Jets in cross-flow
Visualizations (Q-criterion isocontours colored by spanwise vorticity) from direct numerical simulations (DNS) of a laminar tabbed jet in cross-flow, for jet-to-cross-flow velocity ratios of $R = 2$ and $R = 4$ and tab positions of $\phi = 0^\circ$ (upstream) and $\phi = 45^\circ$, performed using MPCUGLES-Overset
$R = 2$, $\phi = 0^\circ$
$R = 2$, $\phi = 45^\circ$
$R = 4$, $\phi = 0^\circ$
$R = 4$, $\phi = 45^\circ$
