Ferrari F138

[markp]

When the car was rolled into the garage there are pics with orange towels o. the back of the sidepods. they were not over the exhausts but part just behind where these dirt strakes were? Could the new strakes on the nose caused this as they were the only major visible change to the car today?

The picture showing massa's car form the top, published above, is very interesting, as Scarbs on his twitter pointed out, because of the 3 gray dirt traces on top of the sidepods.

Some thoughts about them:
- is it my impression, ot those dark lines seem to start each from a bodywork panel junction line?
-the dust should be accumulated on lines because of the action of vortices: for the inside lines it should be the vortex generated by the small winglets on the sides of the chassis, for the outer line which is just visible on the lhd sidepod it should be the vortex from the ouside bargeboards of the sidepod mixing with the vortex generated by the indentation of the sidepod upper leading edge
-the deviation of the streakline -dustline to the outside towards the exhaust shows probably the combined effect of the bockage from the central part of the car (high pressure from the top of the beam wing also) and the entrainment of the fast exhausts pulling the upstream. If so, I did not expect this effect to be so strong - maybe it is something else.

Edit. also from the same picture it seems that ferrari are running a unique shape of floor -rear wheel strake: oblique instead of aligned with the longitudinal axis as most other teams, but with an oriented and rounded leading edge. What's going on?

If those are vortices originating from the front of the sidepods, they are awfully precise and consistent, which I doubt happens over a range of speeds. Since they end up exactly at the exhaust exit, could it be that they show the line of hottest temperature inside the sidepod's skin, where the water dries up the fastest leaving all the muck in place? That would be a result of internal aerodynamics, which should be more consistent than external, IMO. Maybe that's giving away the position of their Helmholtz chamber?

This exhaust is new, right? It's a lot lower, a lot more aggressive, it even seems that the bodywork somewhat before it is changed...

Looks like the exhaust is going red bull like, but not connecting with the floor though

Ferrari said that among other parts, they're also trying a new floor, still to come maybe?

[beelsebob]

No, your eyes are just tricking you. That exhaust is the same one as before.

I'm fairly certain that's lower - than the launch spec at the very least, which was comparatively high against other cars.

[beelsebob]

Yeh okay, having seen that other shot, it is indeed lower – is that a panel under it making a tunnel too?

[dren]

No tunnel, it just appears to be lower, more like Mercs.

Also, notice the "red bull hump" above the exhaust
