摘要
对附加不同整流装置的圆柱体横向单自由度涡激振动特性进行了系统研究。重点分析了约化速度3.0≤U_(r)≤12.0范围内,附加不同整流装置的圆柱振动幅值,受力系数,振动频率和泻涡模式。研究结果表明:附加不同整流装置的圆柱体其水动力特性较附加整流装置的静止圆柱体复杂很多,采用附加整流装置的静止圆柱体绕流结果评价整流装置性能好坏欠妥。
Here,characteristics of transverse single-DOF vortex-induced vibration of cylinder with different rectifying devices were systematically studied.Vibration amplitude,force coefficient,vibration frequency and vortex shedding mode of cylinder with different additional rectifiers were emphatically analyzed within the reduced velocity range of 3.0≤U_(r)≤12.0.The results showed that hydrodynamic characteristics of cylinder with different additional rectifiers are much more complex than those of static cylinder with additional rectifiers;the results of flow around a static cylinder with an additional rectifier are not good enough to evaluate the performance of the rectifier.
