本文对孤立圆柱的涡激振动和串联圆柱的流动与振动的最新研究进行了选择性的回顾;一个共同的线索是提出的主题是作者特别感兴趣的。本文介绍了雷诺数对孤立圆柱响应的影响，并讨论了利用强迫振动的最新发展。自由响应的圆柱体在直线和横向方向上的响应与仅在一个方向上响应的圆柱体的响应进行对比。本文讨论了两个圆柱之间的干涉问题，并着重讨论了串联圆柱的干涉问题。下游圆柱上的时间平均升力的起源被认为是一起的大振幅的横向振动的圆柱涡共振以上经历的原因。这种尾流诱导振动是涡激振动的一种形式。(C)2011爱思唯尔有限公司保留所有权利。
This paper presents a selective review of recent research on vortex-induced vibrations of isolated circular cylinders and the flow and vibration of circular cylinders in a tandem arrangement; a common thread being that the topics raised are of particular interest to the author. The influence of Reynolds number on the response of isolated cylinders is presented and recent developments using forced vibration are discussed. The response of a cylinder free to respond in the in-line and transverse directions is contrasted with that of a cylinder responding in only one direction. The interference between two circular cylinders is discussed and prominence given to the case of cylinders in a tandem arrangement. The origin of the time-mean lift force on the downstream cylinder is considered together with the cause of the large amplitude transverse vibration experienced by the cylinder above vortex resonance. This wake-induced vibration is shown to be a form of vortex-induced vibration. (C) 2011 Elsevier Ltd. All rights reserved.
