Fluid-structure Interactions and Flow Induced Vibrations: A Review

Abstract

Fluid-structure interaction (FSI) is intensely coupled with the flow induced vibration (FIV) through the motions induced on a deformable or moving structure being subjected to an external or internal fluid flow. This kind of interaction in turn evolves with a variety of flow phenomena having applications that ranges from aeroelasticity to blood flow through arteries. The prime objective of this paper is to review the potential research studies pertaining to a variety of modelling and computational techniques, dedicated for exploring the underlying physics of the phenomena relating to the fluid structure interactions and the flow induced vibrations. Technical revelations related to the dynamic effects of the flow induced vibrations on engineering systems in fluidic environment have been gleaned from numerous research studies and presented. Emphasis is also given on the fluid flow analysis pertaining to the excitation of low-frequency vibration modes in structures at nanoscale for the efficient design of modern engineering systems.
