摘要
通过求解二维非定常不可压缩 Ｎ Ｓ方程，研究了均匀来流中旋转振荡圆柱的流动特性，系统地改变流动的振荡频率、振幅，分析了圆柱的受力特性及尾迹结构，发现了与横向、流向振荡的圆柱相似，旋转振荡也是流动控制的一个有效方法，有其自身的流动规律及特点。
Two\|dimensional unsteady incompressible Navier\|Stokes equation is solved and characters of the flowfield past a rotating oscillation circular cylinder in uniform flow are systematically studied in this paper. By changing the oscillation parameter, the features of the force on the circulor cylinder and the wake behind the cylinder are analyzed. Numerical results show that similar to a cylinder performing oscillation laterally and streamwise, rotating oscillation is a very effective method for flow control.
