Obviously drag is a consequence of flow but primarily due to surface friction, the wing tip vortices that you refer are non consequental in comparison.godlameroso wrote: ↑30 Jun 2018, 12:37
To reduce but not eliminate drag, no drag no lift, did you skip high school physics? Also the diffuser and body itself produces downforce on an F1 car, like the kind poster above you mentioned the car works as a whole.Furthermore every moving object that displaces fluid results in vortecies, whether it results in turbulence or entrained vortecies is another matter.
It's the same for RBR, it's just harder to see. The floor is raised in the section closer to the T-tray, stays horizontal and the outer edge is slanted down to the level of the actual floor. The T-tray is channeling air to the raised section of the floor. The bardgeboards are doing a few things.M840TR wrote: ↑30 Jun 2018, 13:12That leading edge of the floor is so bare

The new nose doesn't work with the device that worked with the old nose, so they can't guide airflow 45 degrees behind the bargeboard inlet, that and the flow stagnation at the edge of the bargeboard means they can't get the amount of downforce they want. The balance is good, they just don't have downforce, they're missing pieces in critical areas. It goes to show how interconnected the total aero of the car is, if two small counter intuitive regions are responsible for so much downforce.M840TR wrote: ↑30 Jun 2018, 13:12That leading edge of the floor is so bare

1 - They're blocking air flowing front to back from disrupting the t-tray air.
2 - They're corralling the T-Tray air flow from escaping from the side and channeling it under the floor.
3 - You can see from the flowvis, the flow of the air in front of the bardgeboard is outward but also downward.
4 - The chicken wing and it's arm preceding it are grabbing the air a guiding it under the floor.
You can see in this picture RBR had 2 bigger chicken wings ...

and in the latest reencarnation, they have 3 HUGE fingers now.

Is that not the mid-wing? And you mean to say that since that is guiding air under the floor Mclaren feel there's no need of the vortex generators on the floor leading edge?diffuser wrote: ↑30 Jun 2018, 22:01godlameroso started referring to it as that.

The front wing does 5 different things, why not this part of the car? It can certainly be made complex enough.
I just think they never got around to that, Prodromu is very methodical I doubt he'd just toss on parts at the floor leading edge without getting all the upstream airflow settled.M840TR wrote: ↑30 Jun 2018, 22:15Is that not the mid-wing?
