| Résumé : | It has been recognized that jets in crossflow are more efficient mixer than free-jets or mixing layers. This enhanced mixing is attributed to the counter-rotating vortex pair. The work of Cortelezzi and al. makes evidence of this by explaining the process involved in the formation of the two counter-rotating vortices. Pulsed jet in crossflow can further improve the mixing of the two streams by changing the nature of the flow. Some au- thors have already studied experimentally the structure of pulsed jet in crossflow. Here, we propose to study the phenomena involved in the formation and development of a pulsed jets in crossflow via large eddy simulation (LES). |
