研究发现后掠圆柱及后掠机翼在一定条件下存在一类既不同于马蹄涡也不同于卡门涡的空间稳定发展的三维旋涡系即背涡。
3) Notoplana humilis
薄背涡虫
1.

4) asymmetric vortices
非对称背涡
1.
The pressure fluctuation on both sides along the axis of the cylinder were compared to the cross-section vortices structure, which educed by the measurement of mean pressure based on the physical model of asymmetric vortices.
在亚临界流动范围内,通过尖拱细长旋成体在无侧滑状态下的脉动压力测量,对大迎角下细长旋成体非对称背涡结构沿轴向的压力脉动特征进行了研究分析,揭示了压力的脉动幅度与频率沿旋成体轴向的变化规律及其与背涡结构之间的对应关系,并对压力脉动特征沿轴变化的原因进行了初步探讨。
