F1 aerodynamics focused on two primary goals: the creation of downforce, to help push the car’s tyres onto the track and improve cornering forces, and the minimisation of drag from air.
Race car wings - or aerofoils as they are sometimes known - operate on exactly the same principle as aircraft wings, only in reverse.
(Down force instead of up force)
A modern Formula One car is capable of developing 3.5 g lateral cornering force thanks to aerodynamic downforce it produced. That means ,theoretically, at high speeds they could drive upside down.
The front wings on the car can produce 25-40% of the cars downforce.
The relationship between the front wing and the track is a delicate one; with the wing generally being more efficient the closer it is to the track. Therefore, the front
wing is low to the ground to obtain as much advantage from ground effect as possible, and generally has one full spanning flap.
The interaction between the front wheels and the front wing makes it very difficult to come up with the best solution, and consequently almost all of the different teams have come up with different designs
Further to these, some teams use ‘splitters’, which are vertical fences, attached to the undersurface of the front wing, to assist the endplate
The rear wing is a crucial component for the performance of a Formula One racecar.These devices contribute to approximately a third of the car’s total down force.
Rear diffuser consists of many tunnels and splitters.It is designed to carefully guide and control airflow underneath the racecar. Essentially, it creates a suction effect on the rear of the racecar and pulls the car down to the track.
Because of the complexity, today’s Formula One cars are designed with CFD (computational fluid dynamics) and CAD (computer aided design) that allows engineers to design a car, and immediately simulate the airflow around it, incorporating environmental parameters like traction, wind speed and direction, and much more.
Investigated in the early 1700s by Daniel Bernoulli, his equation defines the physical laws upon which most aerodynamic concepts exist.This now famous equation is absolutely fundamental to the study of airflows.Every attempt to improve the way an F1 car pushes its way through molecules of air is governed by this natural relationship between fluid (gas or liquid) speed and pressure.

So that are some little and simple explanation on how F1’s aerodynamic works.
