Renders and animations of Neko simulations.
A direct numerical simulation of the passive scalar evolution in the von Karman turbulent boundary layer induced by a rotating disk, highlighting near-wall streaks and the larger spiral organization that emerges farther from the wall.
A canonical flat-plate turbulent boundary layer visualization, showing the developing vortical structures.
Rough-pipe flow at friction Reynolds number 2000. The image shows slices of streamwise velocity.
A simulation of the Flettner rotor, a device that leverages the Magnus effect to generate propulsion.
Slices showing coherent temperature structures in a shear-convective atmospheric boundary layer. A large-eddy simulation with the buoyancy-corrected Vreman model.
