2012 Exhaust Blowing & Coanda

[CHT]

I would imagine Adrian Newey had been cogitating about it for quite a long time before that.

Adrian Newey COPIED the competition. Happy to burst your bubble! What a brilliant idea!

They needed less than one week to make their copy after seeing what the other guys were up to.

and they only need 2 days of interrupted testing to get the copied design ready for Melbourne, make every teams wanting to copy their design and fans chatting about how RB8 exhaust system work. How brilliant is that?

Probably

Not buying it. Newey's solution is much more evolved and mature. He just waited to show it.

Hope this one helps:

Thanks

What do you think 'capture velocity' means?

Brian

[hardingfv32]

This model lacks two very important influences you cant ignore.
First of all the extension of the air due to a high temperature gradient, which will itself induce a significant speed. And second the air stream flowing around the exhaust, which keeps the exhaust gas concentrated in a clear stream.

1) Expand on 'the extension of the air due to a high temperature gradient'.

2) Of coarse there is no way for us to know if the air stream helps or hurts exhaust gas concentration.

Newey's solution is much more evolved and mature.

Can you please demonstrate how it is 'more evolved and mature' when compared to say McLaren.

[make every teams wanting to copy their design and fans chatting about how RB8 exhaust system work.

What evidence is there that the other teams want to copy the this 'copy'?

Fan talk about an exhaust system is clear engineering evidence that it must work.

We will find out next week

Find out what? That RB is still at the top of the performance scale as they were at the end of last season. You can not isolate all the other factors that put RB at the top of the scale and develop any data about the value of the current exhaust system. Future race results have no bearing on the validity of this exhaust discussion.

Does flow over the top of the side-pod want to migrate to the sides or the side flow migrate to the top?

Assume a simple on a simple straight flow approaching the side-pod, no special conditioning. Why would not the top and side flows hold their ground as they flow to the rear?

Thanks for asking so nicely.

I don't know about demonstrating, but the bridge/tunnel is where I would point you as a start.

I too am of the mind that Newey was late to the party with the "McLaren style exhaust". As far as RB being more evolved and mature is a strange comment as in engineering less is more and McLaren's solution is far more simplified and elegant.

The RB solution seems to seriously compromise their own philosophy of ensuring excellent flow around the rear of the side pods over the diffuser.

As I have said before, it makes no sense bringing such a solution to the last test and run the risk of weather and accidents getting in the way of measuring its performance. RB were either behind the curve or massively over confident.

I agree with your last statement, but not the first. What makes you think RB has compromised the airflow around the rear of the sidepods? I don't see it that way, and I don't remember anyone else thinking the same(as you), so I'm just wondering.

[hardingfv32]

What makes you think RB has compromised the airflow around the rear of the sidepods?

Is this not a compromise, the flow splitting and going to two different locations.

First I would have to believe that's what the exhaust does and I don't. Secondly, I believe Newey does everything for a reason even if it's unbeknownst to us. He could have chosen many different solutions, but chose this one. Obviously he knows something we don't and I wouldn't pretend to be of equal knowledge with him.
