F1 - What is the Coanda effect - Formula 1 - Wheels Icon

During the 1 F2013 World Cup, we often hear aboutCoanda effect, have already been used in the last season: in the Circus, based primarily onaerodynamics (pending new supercharged engines planned for 2014) a team that can better manage this phenomenon fluid dynamics will increase your chances of winning the title.

TheCoanda effect it is named after a Romanian aeronautical engineer. Henri Coande (known for making the first jet planethen Koanda-1910): after the fire that broke out during its formation, he noticed that during the fall, the flame, as a rule, remained close to the fuselage.

After twenty years of study Coandă he found that a jet of liquid follows the contour of a nearby surface: particles in direct contact with it lose speed due to friction, while the outermost ones tend to maintain their connection with the inner ones and "crush" them, forcing them to maintain their direction. ...

In the aviation world, this concept allows the aerodynamic flow to remain at the rear of the wing. The question of peace F1: in this case, technicians use this principle to increase the rear load (towards the wing or diffuser) using exhaust gas.

Since the exhaust gases can no longer point to the asphalt, all engineers create descending surfaces at the tail end to direct the flow downward. Whoever gets the job done best will have a machine that adheres better to the ground.
