How wing flaps work

How do wing flaps improve the lift coefficient of wings?

Find out in this CFD simulation, where its aerodynamics is explained!

P.s. hope you enjoy the mad drawing skills!

So they're basically producing jets of air, which energizes the boundary layer while entraining upstream air.

The CFD shows a region of air above the airfoil moving faster, I imagine that region doesn't extend upwards indefinitely. Eventually the air above is not being accelerated and becomes a high pressure barrier. What this says to me, is that the wing is part of a virtual venturi tunnel formed between the wing, and the high pressure air that is surrounding and not being influenced by the wing's suction side.

In the engine building world, oval ports flow better than square or circular ports. In the wing world, Prandtl showed the lift distribution, and velocity magnitude form an elliptical shape, this isn't by accident, air is showing you the shape it likes to flow through.

if 3 elements produce such high lift, does separating the main wing into even more element further increase lift ? like 7 elements ? at how many element does the global lift reach a maximum ?
