Mercedes AMG F1 W03

[tomaswrx]

Updates look promising. Let's hope they will work and merc could put their "normal" FW back

[zyphro]

Are these W03-C sidepods new?

I think so.

Everyone who has used the word "coanda" to describe this exhaust layout should stop posting about aerodynamics. You guys are embarassing yourselves. This exhaust doesn't use the coanda effect, as should be obvious, since there is NO CONTINUOUS BODYWORK leading to the diffusor gap. Thus there is no surface for the coanda effect to happen. Well, actually the coanda effect makes air go around the sidepods ("under" the exhaust stream) and to the top of the diffusor but that has nothing to do with the exhaust itself.)
edit: To make this abundantly clear, look at the Sauber and Red Bull exhausts. The have exhaust "ramps" that the exhaust stream stays attached to due to the coanda effect.


It's moments like this where I wish ever post containing "venturi", "coanda" or "fluidic switch" would require mod approval...

Or perhaps you are mistaken?

you're right about the Rake..

I would like to read X's thoughts on the new exhausts. Surely its quality is levels up from last year's patheric "squashed" Volvo-like exhaust?

I hope that in the next two days they will test the exhausts with the original FW, cascades and all and not this one that reminds us of the W02 version. Hopefully they can find some rear downforce that would make the car competitive again.

i'm not home now but can someone post here a photo with McLaren Redull and Sauber exhausts in comparison with w03?

for me w03 exhaust looks little different

The Coanda effect is employed at various stages of the exhaust setup. The actual exhaust tailpipe on the Mclaren points outwards to the maximum the regulations allow and are concealed within the housing that forms the rear of the sidepod. The Coanda effect begins inside the sidepod using the inner wall of the outer edge of the housing to bounce the gases back inboard of the rear wheels.

Also, the airflow from around the sidepod that is channelled under the exhaust and over the diffuser acts as the ramp that some teams have opted to manufacture out of carbon fibre.

I suspect this is the effect that Mercedes will be going for as it clearly has emerged as the benchmark design.

It looks different because they are grafting it onto a different shaped car. The philisophy is common with those teams though. I can't see this being the magic bullet for mercedes though, the area above the diffuser is no tidier than the Force India and they've got a head start with the technology.

Will their running of vents outboard of the exhaust exits act as a gurney thus benefiting exhaust extraction? Or will the lack of laminar flow in that area hinder the exhausts redirecting at speed?


This EBD design appears to be the least intrusive of others, very neatly packaged there.

[NonNewtonic]

The rear of the W03 is actually quite tight and neat! One of the reason why Mercedes had not adopt the McLaren style diffuser is actually to keep clean air flow to the coke bottle

What? The exhaust exit is continued by 2 side "walls" which are angled towards the diffuser. This is most certainly a coanda effect. The difference with red bull and sauber is a slightly different approach towards the downwash effect. Both approaches have their advantages: red bull effectively seperates the normal airflow from the exhausts, while with the mclaren approach the downwash effect is more powerfull. But both uses the coanda effect.

But it's all realtive, isn't it? The Mercedes is already generally faster than the Force India without this exhaust, so they're obviously stronger in other areas. The Force India did get stronger when they introduced this style of exhaust, so it's fair to assume that the Merc will benefit from it also.

The hope will be that, in addition to bringing a tenth or two on its own, the exhaust will help both with balancing the car and looking after the tyres (as a result of having more rear downforce).
