description

National audience; Les phénomènes aérodynamiques instationnaires apparaissant autour de véhicules terrestres lors de rafales latérales, demeurent encore mal connus de par les difficultés, tant expérimentales que numériques, à reproduire fidèlement ces situations en laboratoire. L’ISAE a développé un banc d'essai, inspiré des travaux de Ryan et Dominy (Ryan et Dominy [2000]), dans lequel le déferlement de la rafale sur la maquette automobile est reproduit par un jet latéral mobile longitudinalement. L’écoulement généré par ce dispositif est validé PIV résolue en temps dans ce présent document. L’angle de dérapage obtenu lors d’une simulation de rafale présente une évolution temporelle proche du créneau avec un plateau compris voisin de 25°.
