本文综述了流动诱导空泡振荡的主动控制。本文的动机有两个因素。首先，寻求解决实际问题的解决方案，抑制振荡所造成的流动开放腔在这方面产生了显着的兴趣。其次，空泡振荡控制作为一个模型问题，在不断增长的多学科领域的流动控制。因此，我们试图总结最近在这方面的活动，重点是实验实施的开放和闭环控制方法。除了描述成功，失败，和悬而未决的问题有关的空腔振荡，我们强调的各种致动器，流量传感和测量，以及控制方法的特点，以强调选择，挑战，和流量控制在这个和其他应用的潜力。
A review of active control of flow-induced cavity oscillations is presented. This paper is motivated by two factors. First, the search for solutions to the practical problem of suppressing oscillations caused by flow over open cavities has generated significant interest in this area. Second, cavity oscillation control serves as a model problem in the growing multidisciplinary field of flow control. As such, we attempt to summarize recent activities in this area, with emphasis on experimental implementation of open- and closed-loop control approaches. In addition to describing successes, failures, and outstanding issues relevant to cavity oscillations, we highlight the characteristics of the various actuators, flow sensing and measurement, and control methodologies employed to date in order to emphasize the choices, challenges, and potential of flow control in this and other applications.
