Mercedes AMG F1 W04

Wait, isn't that a tunnel?

[beelsebob]

Isn't the coanda exhaust supposed to blow inwards where the flo-vis is ? Yet it looks like the paint has barely moved.

What's your take on this guys ?

Also... Is that flow seperation on the last pic ?

No, it's supposed to blow where the strake is, so that it can fall down the gap between the wheel and the floor.

Where?

They`ve tested a new exhaust ramp (or maybe is better to say slope?) position and a new diffuser ...
Could they be blowing now even on the rear brake wing lets as the flow paint pointed out?

The intent of the Coanda exhaust is to blow between the rear tire and diffuser sidewall this enlarging the size of the diffuser which is why raising ride height often amplifies this effect of the system is designed well. We've all noticed W04 running much more rake these days so I believe it's safe to assume the Coanda system is operativ well. Also, on the first day of testing you should recall the fire which actually showed exhaust flow very well, and per my recollection the flow was going precisely where one would want.

beelsebob, ferraripilot,

Thanks for the heads up guys. Being a regular follower I of course know the intent of the coanda exhaust. Just that I didn't know (or thought) the flow was intended to go exactly on the strake on this car. I sort of thought they'd try blowing the inside sidewall of the strake to avoid cooking the rear tyres. And to be honest the front part of the strake looks as if it's bent towards the exhaust to do just that.

On a side note, the strake is surrounded with thermal shielding, but the strake itself is not covered and it doesn't look burnt.

Looks like the diffuser they tried on day 1 of testing.

James Allen stated that the Mercedes and Lotus were very close in terms of times over a stint, as well as degredation.

The floviz on the beam wing (when contrast enhanced) looks very good, along with what I can see on the brake flip-ups. I can't quite tell though with the edge of the diffuser. Looks like it might start to separate a bit there.

Ferrari has a solid single profile towards the inside of the tyre. Mercedes on the other hand simply have 5 profiles.

think they'll close off some of the gaps between the elements on the inside?
It looks like a very skilled technique to mold ferrari's wing though.

Appears like Merc is trying to generate more outwash from the part of profiles closest to the end plates

Mercedes were the first team to put a slot in the front wing. Ferrari have been experimenting with the idea ever since. I'm curious to see whether Mercedes will experiment with the front wing as much as Ferrari have.

I believe the car would have been running pretty slowly in those photos with the flames shooting through the back of the car from the exhaust. At speed the trajectory of the mass flow would change significantly due to the flow around the sidepod being at greater pressure at high speed.
