Exhaust placement

Post

I`m curious about Ferrari exhaust placing ... in his case exhaust flow affects air flow much more than other team`s solutions. Are they trying to exploit higher speed and temperature to create underpressure between upper and lower rear wing or what? Or how warm aero element (let`s say lower wing) is behaving compared to element with simmilar temperature? Less drag?

This really couldn't be addressed in the F10 thread?

The point of a thread for each car is to hold discussions about each car in a single contained place.

I thought that this is good place because I`d like to know how exhaust flow affects air flow and Ferrari is just example because of different solution.

Aha - I suggest you edit the thread title to "Exhaust placement". Might help if you also post some sample pics to illustrate the differences between cars - you'll see plenty in the winter testing thread.

my guess would be that hot exhaustgasses has lover densety and therefore lower pressure than the cooler air flowing over the upper wingelement.

So when the hotter gasses flows under the upper wingelement the pressure diffirences causes downforce.

my guess is that if the exhaust gasses exites early as on the ferrari the gasses has more time to blend and expand the airflow under the upper wingelement.


but this is just guesses..... could be wrong :)
