Air is quite full of itself....

Amusing comment, but air is pretty much nothing. Certainly not full of itself.

The primary aim of bargeboards is to create downwash which increases the effective angle of attach of the floor.

I would have sworn that I read they are flow conditioners to smooth the air flowing into the sidepod inlets and also out away from the sides(outwash).

The aim is to bring "clean" air from above the car down to interact with the front of the sidepods / floor. Obviously the first stage in doing that is pushing air outwards to "make room" for the clean air.

Of course it is, air even has mass. There is static air pressure at sea level, or any other level with land, and perfect vacuums are impossible. Therefore air is always full of itself. In other words air will always try to maintain its pressure and will fight against anything trying to stop it.

Mass has nothing to do with what I'm saying. With gasses, the gaps between molecules are a couple of orders of magnitude larger than the molecules themselves. In those gaps is nothing, so, air is pretty much nothing. That's why gasses are so readily compressible.

This is true like most of those who are full of themselves air has little substance, and is easily worked up. With a little push it literally blows up.

Eh, while your original metaphor was neat, the rest are actually somewhat confusing - sounding more like riddles that aren't helping. Unless ofcourse I am misunderstanding.

Air in a cylinder will move up when pushed by a piston. Air will ignite due to the oxygen content, I agree with the person I was responding to fully. Yes the majority of matter is composed of empty space, even more so with a gas, however air tries to remain at it's ideal pressure due to the mass of air above it pressing down and in all directions. The reason we have air pressure is because of the mass of air sitting above it.

The barge boards push the air off to the sides. Outwash. And that creates the disturbed air that hinders passing.

The primary aim of bargeboards is to create downwash which increases the effective angle of attach of the floor.

With Venturi tunnels you don’t want the air pushed to the sides of the car, you want as much as possible fed into the tunnels. Imo barge boards would be counter productive if used with the 2021 Design.

The vanes at the front edge of the floor are quite aggressively cambered outwards too!

Looking at the 2021 concept given the narrower front tires, weaker front wing, weaker rear wing, and much stronger diffuser and floor leading section, I see huge balance issues. Massive oversteer followed by massive understeer at speed, a set up nightmare getting the ride height correct at the right speed ranges. Not to mention that ride height will be massively critical, and getting the rake of the cars will make or break your season. The floor will generate most of the downforce, and the AOA that floor works at will be even more important than before.

Im pretty sure with the amount of simulations the cars wont be that unbalanced.

With the lack of endplates downforce in the rear will slip away a bit earlier tho. That could get interesting

There's no top surface end plates, but there are end plates.

[FW17]

Will shaped rear wings defeat the purpose of not having end plates?

[MatsNorway]

Not replace. But there might be some attempt if the rules allow to get some of it back.

I sure hate to dispute the aero experts but while watching practice 1 today it sure looked like the barge boards pushed the spray outwards. Some down, some up but mostly out to the sides.?.?

[maunde]

Outwards and up, down or laterally?

Have people claimed anything else?

When Renault mounted the exhaust in the front it too went to the sides. By running the air out to the sides you make the floor work better as it gets to work harder trying to suck air back in under. Same but different to blown diffuser where the air gets blown out of it faster.
