Abstract

Through investigations in 3-D boundary-layers around rotating bodies and curved walls, some similarity in the breakdown process of the primary instability with that of 2-D boundary-layer was observed. The behavior of the shedding eddies (secondary disturbance) which appear at the final stage of the primary instabilities (centrifugal and crossflow vortices, etc. ) are remarkably similar to the breakdown process of the Tollmien-Schlichting wave except that the beginning of so called 'new instability' is not so dramatic as 2-D case which accompanies the 'spikes'.
