Abstract [en]

Results are presented of an experimental study of localized disturbances in a plane Poiseuille flow, with emphasis on the nonlinearities of localized (laminar) disturbances. It is found that the nonlinear interaction (NI) of the center of the structure in general appears in connection with large velocity gradients in the streamwise and spanwise directions of the disturbances. At the outer regions of the composite disturbance, the NI follows the negative amplitudes of the velocity
