Abstract in different language: The flow-field behind an inclined plate was investigated experimentally using stereo PIV method providing all 3 velocity vector components in the measuring plane. Flow structure in several measuring planes perpendicular to the main flow was studied. Statistical characteristics were evaluated in the measuring planes. The downwash angle was assessed as well to consider its effect on the lift generation mechanism. The dynamical behavior was studied using Proper Orthogonal Decomposition of velocity fields in measuring planes. The dominant (most energetic) structures were evaluated and presented. The detected structures are of the form of streamwise vortices combined with high-and low-velocity streaks.
