entrance of a flat plate
 

Hi,

Now, I am investigating the flow around the entrance of a 2-D flat plate having endge-shaped (45 degree) leading endge. The thickness of the plate is 20mm, so bottom line of the plate is 20mm longer than the top line of the plate.

The Reynolds number is around 10^6. And the plate in installed at the centerline of a circulating tunnel have a test section dimention(height 450mm, width 150mm and length 700mm).

It was measured that there are not-small vortex flow starting the leading edge below the plate. And the reattachment point and height of the separated flow is varying in time.

I can't find any reference about it. Could anybody suggest some reference ?
