FLOWDUE TO A POINT VORTEX IN AN OSCILLATING AND ROTATING STRAINING FLOWdistance to its nearest neighbours. The vortex is approximated by a point vortex with circulation Γ, the strain rate has harmonic time-dependence, and the principal axes rotate with constant angular velocity.

VORTEX STRUCTURES IN A ROUGH-WALL CHANNEL FLOWAND THEIR INFLUENCE ON PASSIVE SCALAR wall layer, emphasize that in all cases flow visualizations can be used in a laboratory to have a qualitative picture of the modifications of the high- and low-speed streaks. Joint probability density function between vorticity and scalar gradients show how the bursting events affect the scalar distribution.
