Special attention is devoted to dynamics of secondary vortices in channel corner. The stereo time-resolved PIV method is used to acquire time series of the 3-component vector fields in plane perpendicular to the channel axis. The dynamics of the vortical structures is studied using Proper Orthogonal Decomposition method giving the energetic modes.
