同时由于导流体尾迹内部脱落涡强度太低，其脱落频率也不会对发动机低压转子振动特性产生影响。
Moreover, because the intensity of vortex shedding in the wake of the guide vane is too weak, it's frequency has no influence on the vibration characteristics of the low-pressure compressor rotor.
并且当漩涡脱落频率与杆件的固有频率接近时，杆件会产生漩涡脱落共振或称涡激共振。
Besides, in case the vortex shedding frequency is equal to a vibration frequency of structure, the rod will occur the vortex shedding resonance or called vortex resonance.
计算了圆柱的升阻力系数、尾涡脱落频率等描述绕流问题的主要参量。
Such parameters of flow characteristics are investigated as lift and drag coefficient and vortex shedding frequencies.
