Abstract
Large-scale laboratory investigations of multiple--vortex wake systems provide time-resolved flow velocity fields normal to the wake axis. Large vortices shed off the wings and flaps are identified employing the Q criterion. Their cooperative mechanisms of generation and decay are evidenced experimentally from iso-surfaces of Q and of the axial vorticity ω<sub>x</sub>.
