Ferrari F2012

The reason for the slot ahead of the rear tyre minimize vorticies produced by a spinning tyre.

That's what I meant when I said that such a slot should complement the effect of the exhaust in that area. The slot vortex is stable and predictable, which counters the unstable vortices from the rear wheel by "blowing them away," so to speak.

Like you, I expect the upgraded F2012 to incorporate this solution. I'm sure they want to get that RB style floor/diffuser working if at all possible. I'm also thinking we might see a revised nose. I think a little less abrupt than the current one and will probably also use the Sauber Nose-Duct solution as well. )[/quote]


But why on earth would the team not use this solution, even if it would only improve a tiny bit the performance level of the car??

maybe because this solution does not have positive effects on our car, don't you think?

maybe they've come to peace with the fact that until mugello their 2012 campaign is all about damage limitation, and don't want to waste extra time on stuff that will be (is planned) to be on the car when they update it... who knows...

the thing is, this "update" has already been tested... just like the engine cover, they have a new one, but don't use it at all??

and still, they expose it on front of their stands for evey team to see..

quite strange, no?

As we are discussing internal air flow, rediators and exhausts I thnik this picture will be good to compare the when there will actually be any unpdate on the car.



As we are discussing internal air flow, rediators and exhausts I think this picture will be good to compare the when there will actually be any updates on the car. The internal flow is important and Ferrari said before the season that some components are running more the limit with heat. So in that respect I think that revised mechanical design could be quit a challenge to place the different version of the original exhaust. Sauber C31 incorporated different style of exhaust while if we look at STR7 it has quite similar concpet to what F2012 is using now and we know that because of thier double floor they have more vertical position of rediators. The qestion is where will they channel cooling air if the original concept won't be used. We saw the "coke" engine cover at Chinese GP but this could be only update for Bahrain.

The picture Crucial posted earlier in the thread in my view would have to change the etire shape of sidepods. The downwash over the sodepods would have different effect. Event the current exhaust solution was not optimised in that way. But it acts as extracting cooling air so they let it in that way. It would be interesting to see a simulation of how the downwash over the channel on the sidepods interacts with current exhausts.

One notice on the drag issues. I think is interesting what is causing it. Could be the wings AoA or the entire bodywork. I belive they have to improve Cl/Cd ratio of the car.At last race they were also running shorter gear ratios.

Behind the inconsistent flow and temperature issues with tyres that "Acer" exhaust cause I also presume that thehy didn't direct as much flow down to the floor as they calculated. It would be no suprise to me if the current version that si pointing slightly inwards is actually gests pointed more downwards by the flow over the sidepods than the original position.

There is lot of discussion about aerodynamics issues but I also see that improvement on the mechanical side could be as important.

The under cover aerodynamics are not as good looking as the other cars..

IMHO This is one of the greater problem that the F2012 have, the internal fluidodynamics (undercover aerodynamic) has some bigger "breaking" points, the reason why the car has not a big topspeed.

"Looks like ---" is not a technical comment. Nor were the other armchair aero assessments that I've deleted. It seems the F2012 thread is becoming this year's equivalent to the W02 thread.

Lets have evidence based commentary please. For instance, why not highlight the difference in internal packaging between F2012 and another car? There are plenty of pics in the car threads to do a compare and contrast.

Also, what are good internal aerodynamics? What are they trying to achieve? Where is the flow coming from and go to?

[tok-tokkie]

The colors do denote the side of the car on which they're used, but they're threaded so that they tighten under braking, not acceleration.

I wonder what material those nuts are made from, they look typically anodized to me, could they really be Aluminium?

Titanium also anodises beautifully.

Are these not general comments that would be more suitable in an aerodynamics thread rather than this car specific thread?

[Richard]

Good point about generic aero. Its seems to be a increasing prominent topic, so a generic conversation about the purpose in its own thread might be useful.

With respect to this thread I was trying to prompt conversation identifying where the internal air is going to and from on this car. Is it intended to exploit the acer ducts, or go down the middle? First identify that path and then it will be possible to assess the packaging with respect to internal airflow.

I humbly beg to differ, if it looks right - it is right, that's my motto.

I had not noticed yet how big the central radiator fed by the airbox is.

A lot of cars in the past have monted a rad (usually for gearbox) in that position, but I think this is bigger than usual.

Maybe KERS as well. MP4-26 had gearbox rad and another one under the roll hoop for KERS but Ferrari doesn't have that hole.

We haven't seen any pictures with the Sauber sidepod inlet completely removed, but I assume it looks much like this.
