Abstract

Structures in contact with fluid flow are inevitably subject to flow-induced forces and flow-induced vibration. The common term fluid-structure interaction refers to problems where a flow field affects the position, orientation, and/or shape of the solid, and, correspondingly, the structure modifies the flow. In this talk, we will review our research on tackling the interaction between fluid and structure as a fundamental step in understanding the underlying processes of many engineering problems, such as energy harvesting, aerodynamic flutter, biolocomotion and biomechanics. I review the common causes behind apparently diverse unsteady responses of many systems wherein the fluid-structure interaction and interfacial dynamics play key roles. Then, we focus on representative problems of morphing wings and smart electromechanical structures. Future morphing intelligent air vehicles should be equipped with flow actuators and morphing capabilities to continuously adapt during unsteady flight conditions and retain their aerodynamic performance. We will examine the dominant modes of fluid-structure interaction in morphing airfoil-flap systems and discuss the use of embedded geometrical mapping for analyzing morphing bodies and formulating a fast model-based flow active control technique for shape-changing systems. In the second part of the talk, we discuss fluid interaction with electromechanical structures and see how by smart modifications of the electrical and mechanical time scales of piezoelectric surfaces, it is possible to adjust their fluttering response and attain superior performance. We will analyze directions to develop new devices for applications such as structural health monitoring, energy harvesting, and flow control.
