TL;DR: In this paper, reduced order models leading to symmetric matrix systems are described using static well-posed behavior of the irrotational fluid, and the fluid-structure boundary value local equations, expressed in terms of fluid scalar field variables for the fluid and displacement variables for structure, are regularized for zero-frequency limit.
Abstract: Several reduced order formulations are reviewed in the case of linear vibration analysis of bounded fluid-structure systems for low modal density situations Compressibility effects in the fluid for interior structural-acoustic problems, and free-surface gravity effects, as well as for hydroelastic-sloshing interaction problems in the case of incompressible liquids, are examined Reduced order models leading to symmetric matrix systems are then described using static well-posed behavior of the irrotational fluid In this respect, the fluid-structure boundary value local equations, expressed in terms of fluid scalar field variables for the fluid (and displacement variables for the structure), are regularized for zero-frequency limit

TL;DR: A fully-coupled monolithic formulation of the fluid-structure interaction of an incompressible fluid on a moving domain with a nonlinear hyperelastic solid is presented.
Abstract: We present a fully-coupled monolithic formulation of the fluid-structure interaction of an incompressible fluid on a moving domain with a nonlinear hyperelastic solid. The arbitrary Lagrangian–Eulerian description is utilized for the fluid subdomain and the Lagrangian description is utilized for the solid subdomain. Particular attention is paid to the derivation of various forms of the conservation equations; the conservation properties of the semi-discrete and fully discretized systems; a unified presentation of the generalized-α time integration method for fluid-structure interaction; and the derivation of the tangent matrix, including the calculation of shape derivatives. A NURBS-based isogeometric analysis methodology is used for the spatial discretization and three numerical examples are presented which demonstrate the good behavior of the methodology.

TL;DR: A simplified model representing the interaction between a potential fluid and a linear elastic thin tube is considered, which reproduces propagation phenomena and takes into account the added-mass effect of the fluid on the structure, which is known to be source of numerical difficulties.

TL;DR: A class of low-order models for vortex-induced vibrations is analyzed in this article, where a van der Pol equation is used to describe the near wake dynamics describing the fluctuating nature of vortex shedding and several types of linear coupling terms modelling the fluid-structure interaction are considered.
