THE CONE-SHAPED VORTEXX STRUCTURE IN FLAT PLATE BOUNDARY AYER
-
摘要: 用拟三维流动显示技术观察与分析了平板边界层内的流动结构，讨论了雷诺数Ｒｅ在３００－６５０范围内大尺度结构间的联系，并指出锥形涡的形成是边界层中一系列复杂运动现象产生的关键。Abstract: 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,
