Contrôle des écoulements appliqué à l'automobile, état de l'art, (Flow control applied to the car. State of the art).
Résumé
The control of the flows forms the basis for the work of development in automotive aerodynamics. Apart from traditional techniques usually used, many experimental techniques often developed for aeronautics can constitute effective means of reduction of consumption, noise and stains. These techniques can also be used to improve the safety and the dynamic stability of the vehicles at the time of the phases of crossing, overtaking, entry or exit of tunnel with cross-wind. This article constitutes a state of the art of the new techniques which enable to control the flow and the position of separation lines. For each solution, the experimental conditions are recalled and the principal results presented.
