I guess the question is, you want to capture that upward airflow in order to send a big portion of it into the inlet, or guide it towards the undercut. Or maybe they saw in the wind tunnel that the actual airflow volume that goes towards the undercut is very similar, or even better from what they had last year while finding even more benefits elsewhere using this years concept.Farnborough wrote: ↑22 Feb 2024, 10:43Very interesting flow pattern there in regard to air entry of sidepod.
You can see the entrance is almost in "shadow" of the flow primary direction and looking like it's significantly masked from that aspect.
You can virtually determine the reason they've flipped the entrances on RB to fully capture that prevailing flow volume climbing up the side of the monocoque to more efficient effect.
The whole purpose of a intake is to get as much flow through it as possible, else by default it has to be made larger to meet the target volume etc of cooling requirements internally.Bisonas wrote: ↑22 Feb 2024, 11:13I guess the question is, you want to capture that upward airflow in order to send a big portion of it into the inlet, or guide it towards the undercut.

The cockpit (opening) is a sudden depression on the car and as such the front part of it pulls the air in a bit. Coupled with mandatory curvature of the chassis, you have two "sources" of local low pressure zone while the inlet is higher pressure area. This forces the air away from inlet which is not really what you want all the time, so it needs to be controlled. So that whole area is, by design, sensitive to external disturbances, but cooling and heating are not instant processes so there is no trouble if there is some brief detachment in some conditions.
Good point. I can’t wait until they can use their own wind tunnel to maximise that extra time.Venturiation wrote: ↑22 Feb 2024, 19:49and they more wind tunnel so they can try an improved version
That inlet flow is a bit scary to be honest. Probably closer to stall than what we saw from the RB. It's an aggressive direction change considering the incoming flow angle. The rest of the sidepod viz looks great though.Vanja #66 wrote: ↑22 Feb 2024, 08:54High Res flow vis photos.

There seems to be quite a bit of area in the inner corner towards the chassis, behind the underbite wing that doesn't get much air there, judging by the black carbon with no flow-viz on it, but most of it seem to drop into the inlet further back there.AR3-GP wrote: ↑22 Feb 2024, 23:19That inlet flow is a bit scary to be honest.

The flow-viz has mass (and thus a little bit of momentum) so sometimes it won't turn so much compared to the actual flow. However, you can just make out two streaks of the flow-viz that follow near the fillet on the chassis so it appears to be relatively attached flow. It is definitely a more delicate one however.FNTC wrote: ↑22 Feb 2024, 23:22There seems to be quite a bit of area in the inner corner towards the chassis, behind the underbite wing that doesn't get much air there, judging by the black carbon with no flow-viz on it, but most of it seem to drop into the inlet further back there.AR3-GP wrote: ↑22 Feb 2024, 23:19That inlet flow is a bit scary to be honest.
