THE CONE-SHAPED VORTEXX STRUCTURE IN FLAT PLATE BOUNDARY AYER
平板湍流边界层内的锥形涡

The quasi-3D flow visualization method is used to study the coherentstructure in tiie flat plate boundary layer at low Revnolds number,It was found that theformation of the cone-shaped vortex plas an important role in the large eddy structures ofturbulent boundary layer,
