3D vortex shedding behind a circular
cylinder (Re=100,DNS,J.Dijkstra)
DES, Re=105, Iso-surface of Q criterion
(0.4) for turbulent flow around NACA12
with angle of attack 60 degrees
LES of a turbulent jet. Back wall shows a slice of the dissipation rate and
the bottom wall shows a
carpet plot of the mixture fraction in a slice through the jet centerline, Re=21,000 (D. Glaze).
