Secondary vortical structures in a straight channel of rectangular cross-section are studied in details experimentally. Special attention is devoted to theirs dynamics. The stereo time- resolved PIV method is used to acquire time series of the 3-component vector elds in plane perpendicular to the mean ow. Dynamics of the vortical structures in the vector elds is studied using Proper Orthogonal Decomposition method. The dynamical modes are shown.
