Short-time averaged velocity fields allowed the construction of streamlines showing that the separation is topologically of an open bubble type with a span-wise quasi periodicity. The entrained fluid is continuously released by the front vortex which breaks out of the separation bubble in longitudinal streaks. The topology of this dynamic behaviour is described and confirmed by streamlines and vorticity lines.
