How is the geometry of slotted flaps and slats designed?

Because of structural complexity and difficulty in sealing the slots, Fowler flaps are most common on larger airplanes Single-slot type wing flaps; Adjusted

To improve the efficiency of the flaps, air can be accelerated through the slot Same as single-slotted flap, only to a greater degree Triple slots
