Aerodynamic Stall - Wing Profile Fluid Mechanics

[TheSchmidi093]

what program did you use?

[WindWisperer99]

I know what the boundary layer is and how to remove it

[Belegetme]

Do you use Ansys?

[1254261]

Needs more 'draft', punk ;)

[SEThatered]

I wonder why 0-shaped wing has stall angle as big as 55°, where the convenient wings stalls at 15-24°?

....COOL

This airfoil is generic, based on a NACA profile. Regarding Photoshop...I'm positive it takes less time to simulate this in CFdesign ;)

[doppeldeluxe]

Isn't It just Photoshop? ;-) 

[KimiThePilot]

could somebody please help me out and tell me what exact airfoil is? NACA ...? or what is it? thank you very much! I really appreciate it!

@KimiThePilot

Airfoil : surface (as in a wing, propeller, etc.) designed to aid in lifting and controlling an aircraft by means of air currents (Aeronautics)

I love it... thanks for upload it. 8)

[toranoko2003]

please help me with a tutorial for this animation

i hear the guy who made this died in a plane crash the VERY NEXT DAY!

[sobeita]

Is this supposed to represent a live demonstration, or are those patterns anticipated for each of those particular angles?

[slimjim8201]

For this particular wing profile, stalling begins at an angle of attack between 13 and 14 degrees.

@slimjim8201 yea thats typical for small cessnas too

[slimjim8201]

sjh7132, the wing is considered stalled when the flow no long remains "attached" to the airfoil surface and lift is reduced. This detachment or separation results in turbulent, lower speed flow near the wing surface. Knowing Bernoulli's principle, as the flow speed is decreased, pressure increases. In the case of an airfoil, this translates to an increase in pressure on the top surface of the wing, effectively reducing the overall lift generated.

[chujciwdupedwarazy]

@slimjim8201 Max lift occures after stall.

[sjh7132]

At what point is the wing officially considered stalled? When the flow starts to separate from the top? When it's completely separated?

finite element analysis

[slimjim8201]

Yes, CFdesign uses an FEA approach to CFD.

[Adrianrff]

is this finite element method?
