Ok, now I´m eager to read that articleturbof1 wrote: ↑Tue Jun 12, 2018 1:18 pm"all those researches" is making it sound like this topic has been around for decades . It has been somewhat researched properly in 2007/2008. It has been MUCH better researched the last months. The issue with turbulent flow, and I am spoiling an upcoming article a tiny bit here, is that it is VERY hard to accurately simulate virtually. To put it in the most simple terms: to do Direct Numerical Simulation realistically, which would yield the most accurate results, you'll need a quantum computer.
However, approximations under RANS and especially under LES can give good accurate results. Computional power keeps growing, and therefore will keep giving better and better results. Almost 10 years after the first serious attempt of reducing turbulent wake in F1, the changes next year and especially in 2021 will hit much closer to home due better, more accurate data.
Nobody is going to claim you can nullify it. Neither do you need to. Nowadays you need around a 2s pace advantage to overcome the turbulent wake penalty.
EDIT: I don't want to sound like turbulent flow itself has not been researched for decades. It is because it so value for teams to improve their aerodynamic platforms. The case of overtaking & turbulent flow however is something of the last decade, and even then only at a couple of periods.
But I keep skeptical, it was Bhall who conviced me dirty air is low energy air so even if you understand the wake, you cannot get same DF than the car in front on clean air
But if possible, that will surely be the best solution
