平板湍流边界层内的锥形涡

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,
