Hi man, I was thinking about Bernoulli principle and Reynolds numbers. Maybe that "trick" helps them ith this principles.

Vortex in cars with some kind of ground effect, is used to reduce presure below the car extracting air from beneath and enveloping the top of the car increasing pressure there. Some time ago they have some difficulties to mantain the vortex trough all the car lenght, now it seems they've successed.

When I look to nowadays F1 cars, with all the ventings and openings on their top surface I only can think about this. In the past exhaust were placed so they blow just on the diffusor tunels so they accelerate the air exiting the car and then increase ground effect. Today it seems they're using a different strategy, I'm not able to onder about anything but vortex effect.
