Ferrari F14T

The blog post above is totally baseless. Please don't perpetuate some rumor that the f14t has a problem with "sidepod drag".

this ferraris need more traction as they slide more than their rivals .........

Hi NuB here, I agree with your assessment and what I do see is that there is lateral separation of airflow on the corners and not drag as such.

I think the post has major flaws in assessing the issue, but no doubt the short station of the side pod with an abrupt tapering in the 65% range of camber would indicate laminar separation when cornering from the inside (side closes to the corners) and creating a differential in pressure on the outer side... generating more Cl on that side which is contraindicative of combating centrifugal force... So... the OP blog post was incorrect in claiming "drag" but is correct that the shape of the Ferrari is indicative of this problem. You can see in the picture posted as some of the airflow around the bottom of the side pod, the fluid creeps upward and forwards which is more indicative of turbulent flow. My guess anyways...

nice pictures ....

As expected nothing visually new.

I really do not understand people who will criticise a post and analysis without providing alternate analysis in rebuttal. The blog post above is not a "rumor" it's a hypothesis that is tested via analysis of aero concepts. If you want to criticise, address premises that you believe are false, or concepts/principles that you believe to be incorrectly interpreted or applied.

You are just taking cheap shots and not adding any fodder for discussion of the car.

The front wing is not develop as rivals, look quite normal
Rear end is quite fat, they should try to smooth the side pole to make more air to the rear to generate more downforce

Sidepods seem different. As far as I can remember the old ones were wider at the floor than at the top, now it seems to be of a smoother, shorter profile.

I agree, the side pods have definitely got bulkier towards the back.

The sidepods were changed in Spain.

I agree mostly with what you said about spotting some flow reversal, however, I disagree about it being an issue worthy of hand-wringing. Ferrari have what is obviously the third quickest chassis but I feel they are much closer to the front in terms of chassis performance than they have been. I think downforce-wise they are near as dammit to the Bull and the Merc, however Red Bull seems to have much better forward traction out of slower corners mechanically, while Merc probably has a chassis roughly equal to the Bull(rb10 probably has a small df advantage) but with a huge power and driveability advantage.

I'm not taking cheap shots at all. I am working on a degree in aeronautical engineering, and frankly, some of the "analysis" I see in aerodynamics insults me. I don't go on forums for hardcore computing and start throwing around lies made up of terms I don't even understand. People should at least read some aerodynamic texts before making bold claims. Reading some of the armchair analysis on a topic as complex as aero actually makes people dumber. I don't like that. I just feel people should make it clear that they're doing nothing but stabbing in the dark instead of implying that they actually know what they're talking about.p

Just looking at the rather steep aft facing angle on the side pods isn't enough to conclude that he flow separates there. I agree with Pierce, the video shown is useless - it doesn't look like the results of a real CFD run (how could it be without the actual 14T car?), but like a too narrowly focused look at just one flow path while ignoring other aspects of the flow.

The flow is a complex 3D field. I could just as easily argue that the air pushed downward from the split point of the side pod exhaust extension (just above the WEICHAI logo) would help keep the flow attached at that steep adverse slope.

Only Ferrari knows what's actually going on at that location. The rest of us are just guessing, so making a claim that the side pod has a drag problem is groundless.

Best look of the Ferrari PU so far.
