Abstract

The problem of vortex shedding, which occurs when an obstacle is placed in a regular flow, is governed by Reynolds and Strouhal numbers, known by dimensional analysis. The present work aims to propose a thin films-based device, consisting of an elastic piezoelectric flapping flag clamped at one end, in order to determine the frequency of vortex shedding downstream an obstacle for a flow field at Reynolds number Re∼103 in the open channel. For these values, Strouhal number obtained in such way is in accordance with the results known in literature. Moreover, the development of the voltage over time, generated by the flapping flag under the load due to flow field, shows a highly fluctuating behavior and satisfies Taylor's law, observed in several complex systems. This provided useful information about the flow field through the constitutive law of the device.

摘要

当在规则流中放置障碍物时会出现涡旋脱落问题，该问题由通过量纲分析得出的雷诺数和斯特劳哈尔数控制。本研究旨在提出一种基于薄膜的装置，该装置由一端固定的弹性压电拍动旗组成，以便确定在明渠中雷诺数Re∼103的流场中障碍物下游的涡旋脱落频率。对于这些值，以这种方式获得的斯特劳哈尔数与文献中已知的结果一致。此外，由于流场负载，拍动旗产生的电压随时间的变化表现出高度波动的行为，并满足在几个复杂系统中观察到的泰勒定律。这通过装置的本构定律提供了有关流场的有用信息。
