This paper describes a method for describing and quantifying the vibratory behaviour of interacting structural/fluid systems based upon reference to the relative energy associated with each of the sub-systems. The particular case selected is that of a circular plate in interaction with a cylindrical fluid cavity. A theoretical analysis is performed, based upon the Euler Bernoulli and Helmhotz e...

This study presents a numerical investigation of 2D flexible flat plate dynamics, immersed in fluid flow with Reynolds number, based on its chord, 2000. The is animated by forced sinusoidal pitching movement, whose amplitude 10∘ from leading edge. Various materials are considered for the structure, rigid to more ones. Fluid-Structure Interaction (FSI) effects taken into account using partitione...

this study investigates natural frequency analysis of an fg composite rectangular plate partially contacting with a bounded fluid. the material properties are assumed to be varying continuously through the thickness direction according to a simple power law distribution in terms of volume fraction of material constituents. wet dynamic transverse displacements of the plate are approximated by a ...

in this paper, a rectangular sandwich plate with a constrained layer and an electrorheological (er) fluid core is investigated. the rectangular plate is covered an er fluid core and a constraining layer to improve the stability of the system. the two outer layers of the sandwich structure are elastic. the viscoelastic materials express the middle layer behavior under electric field and small st...

We study thermal, fluctuation-induced hydrodynamic interaction forces in a classical, compressible, viscous fluid confined between two rigid, planar walls with no-slip boundary conditions. We calculate hydrodynamic fluctuations using the linearized, stochastic Navier-Stokes formalism of Landau and Lifshitz. The mean fluctuation-induced force acting on the fluid boundaries vanishes in this syste...

We are interested by the controllability of a fluid-structure interaction system where fluid is viscous and incompressible structure elastic located on part boundary domain. In this article, we simplify considering linearization replacing wave/plate equation for heat equation. show that corresponding coupling Stokes equations with at its null-controllable. The proof based Carleman estimates int...

The dynamic behaviour of a circular plate in contact with fluid and resting on two-parameter elastic foundations is of interest in the field of geotechnics, structure, highway, railway, oil and gas and mechanical engineering. In this work, the dynamic behaviour of circular plate in contact with fluid and resting on Winkler and Pasternak foundations is investigated. The coupled differential equa...

We numerically investigate the fluid–structure interaction of thin elastic cantilever micro-structures in viscous fluids. The Kirchhoff plate equation describes dynamics structure, and a boundary integral formulation represents fluid flow. show how displacement spectrum structures changes as geometry is altered from narrow beam to wide liquid. For beams, exhibits only few resonance frequencies,...
