| 图13 不同路径以及对应的尾迹随时间的演化, 每幅尾迹图的上下图分别为该时刻的正视图和侧视图 (a) 小振幅不规则振荡运动($L/d = 2$, $Re_{d} = 449.02$) (b)大振幅低频振荡运动($L/d = 10$, $Re_{d} = 474.60$) (c)高度非线性运动($L/d = 2$, $Re_{d} = 1304.29$) ($d)$直线运动($L/d = 10$, $Re_{d} =149.76$) |
| Fig.13 Examples of the time of evolution of three-dimensional path and corresponding wake , the upper and lower parts of each wake diagram are the front view and the side view of the time, respectively, (a) for the low-amplitude irregular motion ($L/d = 2$, $Re_{d}$ = 449.02); (b) for the high-amplitude fluttering ($L/d$ = 10, $Re_{d}$ = 474.60), (c) for the highly nonlinear motion ($L/d$ = 2, $Re_{d}$ = 1304.29); and (d) for the rectilinear motion ($L/d$ = 10, $Re_{d}$ = 149.76) |
