Questions

  Issues to be resolved for leading edge stall:

• Does the separation arise in the leading edge region or move in from the wing's trailing edge region?
• Can separation be avoided for all times with suction?
• Can separation be avoided for all angles of attack?
• At what location should suction be applied?
• Can suction be applied at a single location (through a single slot) or should it be applied over a region?
• If the latter, over what sort of a region?
• What is the minimum amount that needs to be sucked? Is the minimum suction volume indeed inversely proportional to the Reynolds number?
• What is the effect of unsteadyness?
• Can we apply suction in a better way?
