摘要

本文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。

Abstract

This paper systematically studies the transverse-only vortex-induced vibration of a circular cylinder with different additional rectifiers. The response amplitude, force coefficient, vibration frequency and vortex shedding mode of a circular cylinder with different additional rectifiers are analyzed at 3.0≤U_r≤12.0. The results show that the hydrodynamic characteristics of the circular cylinder with different additional rectifiers are more complicated than fixed cylinder with additional rectifier. It is not good to evaluate the performance of a rectifier based on the results of a fixed circular cylinder with additional rectifiers.
