Viscous flow past a flat plate (1 MB)

(left) vorticity, (right) streaklines. The plate is of length 1. Only half of the plate is used in simulations. Symmetry of the result is assumed about the centerline x=0.  

Dynamics of a Lamb dipole near a half plane wall (217 KB)

The dipole is one diameter away from the wall. Vorticity is positive in red and negative in blue.
