Abstract

This paper presents the first documented investigation of a flow-induced vibration phenomenon referred to as dual cantilever flutter (DCF). The purpose of this research is to introduce the concept of DCF and to help understand the key components that cause it. If unaccounted for, vibration caused by DCF has the potential to cause catastrophic structural damage or unwanted acoustic excitation. DCF may also be used as an effective energy harvesting method. The most attractive feature of DCF for energy harvesting is that it provides a robust type of broadband, flow-induced excitation. This paper will present an experimental and analytical study on a novel, solidstate, DCF energy harvesting device. Results will include CFD simulations that were setup and executed using ANSYS-CFX.
