When the season started and presentations, it was generally read and heard that Ferrari had an aerodynamic design simple and not too revolutionary, without major complications or innovations as they are expected to later with a revolutionary design of a diffuser phased, rumored, could be triple or even a larger number of layers.

When I saw the design of the upper part of the pontoons and the channel that keeps the upper flow "drain" to the side and the soft lines of the final part of the hood, I felt a sense of effectiveness and forcefulness without fanfare I was impressed. It would be unfair to say now that my intuition did not fail me because the beauty, the strength and fineness of lines does not guarantee effectiveness but the truth is that Ferrari has done a great car, or so it seems so far.

But one of the major contributors to ES gave us the picture via a link and has opened my eyes so I begin to understand the dedication shown by the staff of Cavallino leaving the rear of the F10 to view it just like that run on the track, while in other situations have tried to hide the diffuser and the flat bottom at all costs. However, in the form of flash reached us this picture stolen from a parapet between curves that opened my eyes and put my elucubrar neurons.

First I have put a photo of the speaker the F60 before the change to Double diffuser, then the modification of the F60 and the F10 which heads this post. Then do a color scheme with the revolution that has implemented this season that Ferrari has cast us on the sly or brazenly, because we have before our eyes. So much so that I will connect the video that one of our commentators linking us in a McLaren mechanic did spy Paripe blatant playing cat and mouse, trying to see the back of the F10 and calling the attention of cameras, while his companion, much more discreet but with camera in hand, was quiet and effective work of seeking the secrets of the enemy.

Come for the analysis. At the beginning of last season and before the FIA change of opinion about what they were "holes", Ferrari presented to us as more than half of the grid a simple diffuser, and exhaust vents and the engine behind cold air that spread over the flat bottom freely left behind "without science" to create ground effect.

With the arrival of Double Diffuser provided by Brawn, what we had is that some of that flow of air running along the underside of the car was extracted by the rear axle, was heated by heat from the engine and was injected just above the diffuser conventional forcing the cold air coming from the bottom of the car to occupy the warmest place for the difference in temperatures and densities and therefore pressure, firing air flow and producing a greater angle greater downforce the rest, except for Newey had begun to play with heat and cold of an innovative and within the philosophy that supposedly had the rule change.

We will try to explain a little more thoroughly how the double diffuser because then I think we understand better the evolution of Ferrari. The hot air is more restless and tends to expand as you go outside and create a low pressure. Cold air coming from the flat bottom (it has high speed and low pressure venturi effect = ground) to reach the edge of the diffuser tends to follow the shape of the (Coanda effect). This concept is important and I shall give an example for better understanding. It's like when you lean a full glass of water slowly and directly, instead of falling, water tends to just stick to the glass, hence it has to be very wise to transfer a liquid from one container to another if you shed a few drops, (the iced coffee in the bars is almost impossible.)

We had stayed at the time the air leaves the flat bottom at high speed and low pressure and tends to follow the shape of the diffuser. But right now, having more space expands and slows down and produces a high pressure. This occurs right near where we have the low pressure produced by the expansion of hot air, rather just above, and the cold air to a higher pressure tends to occupy the space of low pressure that has left us the hot air so it is as if the form of heat diffuser lengthen the curve, if you look, the shape of a spoiler, but a spoiler to the height of the shaft ensures a higher downforce if not inyectáramos hot air.

Looking at pictures of the rear cars of last season, with the ban on gill and ventilation systems, designers were forced to remove heat from the most convenient way, which generally took advantage of the back of the cars for this function or areas near the driver's seat. This year, having learned from the use Newey gave the heat, Ferrari has taken a step further. In the early preseason Cavallino rumored that the broadcaster would present a triple or phased it would be a revolution but, apparently, the only thing that stood out was to have the output of flow drawn from the bottom of the car to the "first" layer of the diffuser somewhat exaggerated and trapezoidal different design model "smile" established by Brawn in 2009.

But seeing the image that links us in a comment to the previous entries, we can see how they have evolved. Those of Manarello have prolonged heat output of the engine in a tube that goes just above the trapezoidal duct exit, so we have a heat flow just above what it was before the Double Diffuser. We then, as you can see in the picture that now would be the second flow out of the trapezoidal duct that draws air from the bottom of the car.

Here I want to make a point to try to give an explanation of what I think has caused this output is so great (no longer motivated by an extensive study comments and rumors of journalists) and is I think they use that flow for cooling innovative gearbox which apparently been reduced and relocated to compensate and focus pesos. Another explanation might be to cool the fuel that so many headaches has brought to other teams such as McLaren.

Leaving the area of extensive study, we continue the argument and now we have the F10, a hot air flow coming from the engine, we have a second "step" which is the extract from the bottom of the car ( until now was the first step of a double diffuser) and then the third flow of cold air coming from the air diffuser is running along the underside of the car creating a floor effect. Therefore and in view of all Ferrari has planted the first triple or phased diffuser, using the same heat than other currently used to direct the flow of air that surrounds the car.

Because I have hunted images confirm this theory and I could compare with other cars. We could hear the shots "warm" of changes in the back of McLaren in Montmelo with modifications in the area of leakage and lower hood and if you compare with the photo of Ferrari, you will realize that the draw of Wokin heat in a much more advanced position in some shows that it takes about the same height as the exhaust, whereas the channeling of Ross is just above the diffuser.

Ferrari has taken a further step in the development of treatment at different temperatures flows so well that gave Brawn in 2009. Much remains to be crumbling in the rear of the F10, mainly on the bonnet and the bottom of the diffuser and the flat bottom but we'll leave it to the next entry.
