Compared to the other teams Ferrari seems more concerned in turning the flow on top of the diffuser outboard section, while Merc and RB are trying to get outwash with the internal diffuser flow. Less expansion of the internal volume on the Ferrari.mikhak wrote:Aggressive outwash vanes on the outboard diffuser top. Strange how different they are to the upwashing brake duct winglets in front and the diffuser gurney winglets behind.

Interesting flow pattern on the outer edges of the diffuser. Seems the rear brake duct fins and rear wing end plate serrations are working as advertised... =D>f300v10 wrote:https://www.formula1.com/content/fom-we ... 584711.jpg
Someone believe that those overstructures at the top/end of diffuser may generate aerodynamic downforce or maybe could increase the drag effect?henra wrote:Interesting flow pattern on the outer edges of the diffuser.

It appears as if they really create a low pressure area at the side of the diffuser (flow patterns in the diffuser directed towards the outside of the diffuser opposite to normally expected pressure gradient), thereby increasing effective expansion volume of the diffuser and moving air into the rear tire wake.Fede90 wrote:henra wrote: Someone believe that those overstructures at the top/end of diffuser may generate aerodynamic downforce or maybe could increase the drag effect?
I would say it looks as if they can largely avoid influx from the sides. The diffuser's edges are swept upwards on the outside and in combination with the massive brake duct fins look to be able to expand the rotation to the sides thereby reducing influx of air from the side.bhall II wrote:Pretty normal...
That is clear. The question to me rather is: Do you really want a vortex there behind the car? And if so: why? To shield against the tire wake? Other than that I can see no reason what benefit a vortex behind the car would bring.bhall II wrote:The high-pressure influx from the sides is necessary for vorticity. Without that, there can be no force-enhancing edge vortices.
Think about it: what conditions are required to create a vortex?
