Summary

The process of three-dimensional distortion of previously two-dimensional disturbances was investigated in a rectangular channel. For the first time the three-dimensional structures at the breakdown station of the two-dimensional wave were studied by flow visualization. It was shown that the structures have forms identical to ∧ -shaped vortices in a boundary layer of the flat plate. The spanwise spacing of the ∧ -shaped vortices is quite independent of the mean flow velocity and of the frequency of artificial disturbances.
