Look at these strange vapour trails coming off the rear wing of these F1 cars. They are only visible in certain conditions but are present whenever the car is at speed. It’s the effect that enables flies to fly, and the Concorde to reach such high speeds.
They are called Vortices, and are a natural bi-product of an F1 car’s wings. They produce a lot of drag and ultimately slow the cars down.

So how do you create Vortices?
This is actually easier to explain with a plane wing. As you probably know, a plane wing creates lift by using a low pressure area above the wing - this then literally sucks the plane upwards.
You can see the low pressure area here, where the cloud-like vapour is above the wing. You’re only able to see this in certain conditions, but we will get to that.
But the interesting thing is that at the edges, this creates a strange effect. The air here is able to spill around the edges of the wing, and so, the air from below the wing is sucked around the side by the lower pressure air.
This creates a tumbling, turning effect - starting a spiral of air that creates a mini-tornado, that trails off the wing. This is what we call a vortex.
For planes the vortices are a bad thing, they produce a lot of drag - but are often unavoidable as they are a natural bi-product of having a wing - and you need those.
They are also naturally created on an F1 car. Back in the 80s and 90s, you could see them trailing off the rear wing, sometimes up to a metre long. The rear wing produces about 30% of the drag of an F1 car, and this is part of the reason.

I did not like his phrasing at 0:56 about how a vacuum literally sucks the plane upward. A vacuum cannot exert a force. As an experiment, place your coffee cup on the table in front of you and place your hands either side just touching the cup. Move one hand away. Result - the cup stays where it was. Now put your hands back on the cup and push equally with each hand so that the cup stays still. While still pushing, move one hand away (this is easier to do with two people). Result - the cup moves towards the hand that is moving away (the low pressure side) - not because that hand is moving away but because now the other hand is exerting a force. In the same way, low pressure regions cannot exert a force on a wing - the force is applied by the high pressure region. It's contact with atmospheric gas molecules bouncing off the wing that is pushing it.

The speed cars go at, velocities drivers are exposed to and the materials and shapes the cars are made up of can't outpace safety. That's the reason next year's F1 is going to have significant restrictions on how to generate downforce. Cars are getting too fast.

Of course turbulent air can stay attached. It‘s much better at doing that than laminar airflow. However, dirty air and turbulence are two different things

Agree to an extent, but doesn't turbulent air generally form when attachment breaks down, often through too aggressive a shape or too high angle of attack?

[@Bl4ckDe4th88]

@@laurencedawson7754 no, that‘s detached flow. Air (or another liquid for that matter) becomes turbulent and more energetic above a certain Reynolds number. I think it‘s between 3 and 4k, but don‘t quote me on that. So if you have laminar flow and just make it way faster it‘ll become turbulent

[@laurencedawson7754]

@@Bl4ckDe4th88 kind of, if you are talking about the classic pipe situation or between two surfaces (for example the road and underside of a car) but the dimensions of the pipe or distance between the surfaces are factors and so you are back to the aggressiveness of the shape/ gap for the velocity range you are aiming to work in. The transistion is always related to dimensions, in a hypothetical pipe of infinite diameter, there would be laminar flow at any velocity.

[@Bl4ckDe4th88]

@@laurencedawson7754 I guess that's right, but talking about realistic examples a fluid becomes turbulent above a certain Reynolds number, which is linked to the velocity. Going back to your fist statement, you're probably right, that turbulence forms, if there are aggressive shapes or a stall. But it (realistically) also happens above a certain speed. And that air can stay attached. It won't in the case of a stall, but generally turbulent air isn't being detached just because it's turbulent. And I don't even think dirty air can't stay attached, it's just hard to controll and creates massive amounts of drag. That together with the fact, that it's hard to calculate it's behaviour is most likely why F1 tries to get rid of it.

[@ianturner7635]

Great videos with good explanations. I would just add that vortices don’t create drag, they are a manifestation of the pressure difference. Drag is a combination of friction and pressure forces on rearward facing surfaces. Rw gills for example reduce drag by reducing high pressure on the wing upper surface. This means less pressure difference hence s smaller tip vortex is the result not the cause of less drag.

if you notice in the F2004’s rear wing you could see its moulded to slope down right beside the end plates in an attempt to minimize the drag and create less vortices. The second gen Ferrari powered A1GP cars also had this rear wing design as they are directly based off the F2004 specifically. Some F1 teams still use this too particularly Mclaren

[@conorjones5093]

Well you can use turbulent air to control flow, but it has to be attached to the surface so you have to expedite transition the air from laminar to turbulent flow. This allows the turbulent flow to reattach post transition and can help!

​@Eff yore Feelings Hey buddy. There are literally hundreds of race teams in the UK alone. However most are very small and run by the driver and a couple of mates (for example) and possess only basic equipment. Volunteering with such a team can still be a lot of fun and be greatly rewarding. Many championships, even at the lower end of sophistication, contain teams which run multiple cars and/or drivers. Such teams will employ mechanics etc and may take on volunteers to generally help. Then there are British championships such as BTCC, Clio Cup, F4, F3, GT's etc in which a lot of money is involved. As such there are often openings for competent folk and you can get paid for positions such as data engineer, race engineer, logistics, trucky as well as mechanic and general help. Facilities such as wind tunnels, due to costs, are limited to the top tier championship teams such as F1 and WEC and are also found at companies such as Lola, Prodrive, MSport, WIlliams Automotive etc. To be honest, the majority of employees at such companies will have progressed through higher education and have experience. But I'm sure that someone who displays the aptitude and determination does have a chance. Good luck and enjoy!

btw the biggest vortex come off the flaps (only deployed during takeoff & landing to increase the wing area -> lift in low airspeed) not "wing itself". Cruising speed the airplane has to be efficient, that's why new planes has winglets to reduce vortex off the edge of the wing.

[@WuffiePhoenix]

Its a GREAT Video! Good job!

[@chrisberry6919]

The principle you describe at 0:50 is not the cause of wings generating lift & helping planes to fly. The only thing required to generate lift in any wing is an angle of attack. The Bernoulli principle only makes them more efficient.

[@LazyboyLP]

It is actually not just the pressure that causes condensation. Air can only hold as much water at specific temperatures. As we know, accelerated air cools down (otherwise fans would lose their effect.) If you have a high relative humidity, and warm air, it can hold much more water. But when the air cools down, it loses the ability to hold that water. So the water needs somewhere to go and starts condensing and forming those droplets because the air cant hold the water anymore since it cooled down through the rapid acceleration over the wings. That is also why you see the "clouds" in front of the jet engines from planes because the air gets accelerated so fast.

[@balazsbelavari7556]

1:33 I would disagree with wing vortecies being unavoidable on planes as engineers put lots and lots time into getting rid of them. That landing plane in a sense has 2 sets of wings, one being the real wing and one being the flaps (meant to slow down the plane whilst greatly increasing lift). What we can see in that picture is that the only place these vortecies are made are the flaps of the airplane, as they can't have the parts wingtips can have to reduce these vortecies. There are lots of different ways to (mostly) get rid of these vortecies like tapered wings, wintgips that curve up or down or big bulging fuel tanks on the end of each wing that all stop high pressure air from the underside of the wing to get to the top of the wing around the wingtips

[@onlyGGG]

Wingtip vortices are unavoidable. The induced drag from them may be minimised but they can never be eradicated. Circulation is a fundamental part of lift generation and without the vorticity you have no lift. You see patented objects claiming to prevent them but it is all lies.

[@maddox471]

Fun fact The vortices you can see on the rear wing is actually McLaren’s logo

[@BrandonKent136]

Be careful with how you use the word "turbulence." Technically turbulent flows (higher reynolds number) increases L/D

[@stuart1001]

This channel is so good

[@nicomarroquin1998]

Turbulent air in itself is not a bad thing to have, rather air that has gone through a boundary layer and has suffered a change in pressure compared to ambient air. Flow attachment is critical to avoid flow separation and wake, thus an increase in drag, that’s why in planes’ wings there are vortex generators, whose function is to increase drag and allow for better flow attachment as that is a function of the associated energy that the fluid has.

Can you talk about the 22’ rules about aerodynamic and also about 21’ new rules ? What’s the difference between each other and how does that help or hurt?

The reason why you can see the vortices in humid weather is the moisture is being squeezed out of the air. cool huh

In fact, the vortices in F1 do much more than just a barrier. The so-called Y250 vortices drag the air above each of them to the centerline of the car, which will hit the vanes mounted under the front suspension (Front Turning Vanes). Due to the induced inwash and downwash by the Y250s, the FTVs has quite a large angle of incidence to the incoming flow, which would then act like plane wings and create a vortex on their tips, effectively forming a counter-rotating vortex pair with the Y250. The vortex pair pushes down the air between them, forming an optimum flow field for the bargeboard footplates. The 'nose cape', introduced in Spain 2017 by Mercedes, acts in a similar manner, only to be placed a little bit lower than the FTVs. Apart from the concepts above, F1 engineers would utilize vortices to induce some desired flow field close to the surfaces as well. By opening slots on the bargeboard footplates, the Y250 brings some air through them when being directed outboard by the bargeboards, effectively creating a virtual 'side skirt', preventing tyre wake from entering the undertray. Vortices shedding from upper and lower edges of the bargeboard would gradually fall onto both sides of the undertray, pushing air out as well. Aerodynamic designs of F1 cars are true magic that for most of the time can't be deciphered with eyes: even if the concepts mentioned above have become 'common sense' for F1 aerodynamicists, there are still a huge amount of details, such as the strength, exact position and length of vortices, as well as how they change through the entire aero envelope, that would be understood and manipulated very differently among each team. Making a precise simulation of those vortices is, if not, the biggest challenge in understanding the physical aspect of the car. Under this circumstance, one could say that F1 cars look almost the same only because of the regulations: the ideas and interpretations make each of them a whole different world inside.

Vortex and condensed air or vapour trails are in a sense connected but not the same, like in that drag and downforce are not the same but have an indisputed relation. Aircraft and F1 both have to do with aerodynamics, although in different ways and with different goals.

This is also why you see those upwards fins at the wingtips of passenger airliners .

Winglets

[@faatihh1130]

didnt they add the winglet because of an xb-70 collided with an f-104?

[@pelee1966]

No, actually it is the opposite, because winglets reduces vortexes. Winglets create more drag but makes the the wings more efficient and can lift more.
