W06 Rear Wing Vortex: real or not

Oh look at that!

Nice job of photoshop.

Generally, we have witnessed vortices from cars, when it has been foggy OR cloudy rainy conditions. In normal, clean atmosphere, the vortices aren't observed, as by default, the air remains thinner. Just see how the airflow is monitored in wind tunnels. Essentially, smoky or foggy conditions produce good atmosphere for their visibility.



Although there are loads of photos available on internet showing Vortices from Front Wing tips, from the T tray side and from rear wing tips, but NOT ONE real time photo of laminar flow of air over the body the car OR over the Rear Wing (like the pictures posted above).

Minardi not telling the truth has neither something to do with Mercedes their car. People who have been there first hand have seen that there are obvious differences from the 2014 PU. I'm going to remove the comments about it before it gets out of hand.

That's a vortice from the side plate cutout curling over and interacting with the one from the corner of the wing, not from laminar flow, that's why.

The vortex is clearly photoshop. That whole album of the W06 shakedown has Photoshop lighting effects that would make Michael Bay proud.

Oh come on guys! This photo is from F1fanatic and also, this is taken from day 4! An editorial photographer?! Making lightings to images that's not even possible man

So you're saying that this is photoshop too?

What you are seeing above is side angle of this. Perfectly possible and real time.


Below is a clear PHOTOSHOP. We have never practically witnessed vortices generating from MAIN PLANE of rear wing. Thats just not possible. DEFINITELY NOT THAT MANY STREAMS.

I second that, vortices can be very noticeable, especially in a cool, moist weather. I can see them coming from the flaps of aircraft that pass by my house on way to the airport. Plus, here's another photo showing vortices, though it is not a Mercedes, it serves this little issue. The source of the picture? Scarbs. http://scarbsf1.com/blog1/2011/08/08/an ... ur-trails/

Assuming it's real, the haze behind the main main isn't a vortex at all. A straight aerofoil wouldn't produce a vortex along its span as such but it will produce a sheet of condensation if the conditions allow. This is seen quite often with aircraft wings flying at high angles of attack. Most common is in military aircraft because they often display at high alpha:


It does occur on commercial aircraft too, typically when the flaps are deployed during landing or takeoff:

See how there is a condensation zone bounded by a tip vortex at the ends of the flaps. This is basically what the W06's wing would look like from the rear in that shot above.

If the image of the W06 is real, then the haze is just an indication that, at that point on the circuit, the air was close enough to the dew point that the rear wing's action (it lowers the air pressure below it, don't forget) has caused condensation to occur. It's entirely possible that such conditions occur in small pockets of air and the car and phot just happened to coincide with one of those pockets. We see these pockets every day - think of a hollow in the ground that has some mist in it when all around the air is clear.

The w06 image is real - normal. I do not understand why on this forum there are users who seem to believe they are photoshopped - there are plenty of images showing this on this forum. jerez testing is one of the best places for seeing those conversatio trails, because it is sunny but cold.

[turbof1]

I share that opinion - the image is real. I think the question is: is it really what we think it is? Just_a_fan might be correct on this, it doesn't like a vortex, or atleast the 2 streams underneath the main plane, but like a haze.

The bottom stream is however a vortex, coming off the left endplate. Curiously the right one does not show a visible vortex, supporting Just_a_fan's theory that the car drove through a very localized pocket of dewing air.

Yes, we should not forget that conditions in Europe in January-February are significantly different from any racing weekend. So it is no surprise that we are witnessing something unusual.

[SectorOne]

Someone showed a program here once where you could take an image and see if it has been manipulated.

Here we are seeing cool environmental conditions combined with the pressure drop on the lower surface of the main plane. This adiabatic cooling of the air causes the temperature to drop to the dew point and therefore leads to the formation of clouds.

So you're just witnessing work being done by the entire length of the wing, which is a win for physics.

[NoDivergence]

How anyone can doubt that these are two vortices at the edge of the endplate is beyond me. Very typical, natural, and supported by CFD and wind tunnel.

I mean, come on now...

This is exactly what you see here.

No one is challenging the tube-like vortices trailing well behind the car. What we are discussing are the horn-like structures that travel well above the wing's maximum height.
For starters, a google "search by image" fails to find a very similar image without the "horns". This in itself makes the photoshop close to aonspiracy theory, as the photo would have had to be doctored before ever being posted to the web.
But then, looking at these two together should put the photoshot theory to bed:


Invert the wing and change the camera position... the "horns" are formed at or near the point of maximum convex curvature, below the read wing, and then carried in the upwash to where we can see them. As said above, air being worked very hard, nothing else. =D>
