How is lift affected by angle-of-attack? 升力如何受攻角影響？

Bernoulli’s principle: as the velocity of a fluid increases, its internal pressure decreases.

I am very sorry, but what you say at time 0:50 is INCORRECT.!.
. . .
When that wing is at zero degrees geometric Angle of Attack, (AoA) and it is at level flight, it is THEREFORE generating lift; AND the flow__IS__ Asymmetric! There WILL be some up-wash AND Down-wash!! The air Will NOT FLOW AS SHOWN.!.
That is Incorrect!
.. .. ..
There ARE places around a wing where Bernoulli's Principle is followed, but just about all videos and papers that describe how this happens are wrong.
..
It is also poor physics to say that the flow is related to the venturi effect. This is a very common misconception that says the air must squeeze through a smaller space above a wing. The fact that the air below has a similar narrowing, near the trailing edge of an upturned AoA, CLEARLY shows that this is OBVIOUSLY FASLE science.
The air above the wing does not have a hard wall causing this to happen. The air above is a very soft boundary and there is no venturi effect.
..
The air above a wing meets the trailing edge before the lower air because the negative pressure above forms a Pressure Gradient with the positive pressure near the leading edge that together, accelerate the air rearward.
If you measure the speed of the air above the wing in reference to the ground (zero wind), that upper air actually REVERSES DIRECTION as the wing goes by and is traveling in the OPPOSITE direction of the wing. It is traveling BACKWARDS - opposite to the direction of flight!. this is the result of the high rearward Acceleration due to the steep pressure gradient mentioned above.
.
Lift is not very complex when understood correctly. This following blog steps through it for you rxesywwbdscllwpn DOT quora DOT com/ Put the DOTS back in because You Tube does not like links in the comments.
