Implicit fluid–structure coupling for simulation of cardiovascular problems
International Journal for Numerical Methods in Fluids, 2002Abstract A three‐dimensional (3‐D) transient solid–fluid coupling system has been developed in order to study cardiovascular systems and devices. The system utilized two commercial implicit solvers, which exchanged boundary parameters from separate meshes over a common interface.

Free vibration of a coupled fluid/structural system
Journal of Sound and Vibration, 1972Abstract The beam-like vibration of a fluid/structural system consisting of a cylindrical rod submerged in an ideal fluid enclosed by a cylindrical shell is studied analytically. A method is proposed to find the natural frequency. Numerical results are presented to show the effects of various parameters, and an approximate expression is given for the

A fluid-structure-interaction tool by coupling of existing codes
Proceedings of the 20th European MPI Users' Group Meeting, 2013Fluid-Structure-Interaction (FSI), as a sub-discipline of computational mechanics, has been gaining relevance since the growth in clusters capacity has made it possible to simulate high resolution models. Although some commercial tools already present certain capabilities for coupled simulations, the lack of efficiency of these general purpose programs

A MODAL METHOD FOR COUPLED FLUID-STRUCTURE INTERACTION ANALYSIS
Journal of Computational Acoustics, 2004A modal method is developed for solving, analyzing, and controlling vibration and sound radiation of coupled fluid-structure systems. The method recasts the coupled equation of a coupled fluid-structure system in the classical matrix structural dynamic equation by modeling the acoustic load vector as direct linear function of the acceleration ...

Coupled Fluid-structure Interactions
2017In Fig. 3.1 we show a typical configuration of fluid-structure interactions. At time t = 0 the domain \(\varOmega \subset \mathbb{R}^{2}\) is split into a fluid-part \(\hat{\mathcal{F}}\) and a solid-part \(\hat{\mathcal{S}}\). This configuration is called the reference configuration and we assume that the system is at rest, i.e. v f = 0, p f = 0 and u

Thermal Fluid-Structure Coupling for Atmospheric Entries
ASME/JSME 2011 8th Thermal Engineering Joint Conference, 2011This paper deals with the modeling of aero-thermal aspects of a space vehicle during its entry phase into an atmosphere. We treat the numerical coupling techniques between the external and internal aero-thermo-dynamics (ATD) produced by the interaction of ATD fields with the structural components. The thermal properties induced within the structure via

Analysis of Small Vibrations of Coupled Fluid‐Structure Systems
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1994AbstractThe article deals with the non‐selfadjoint eigenvalue problem arising in the analysis of linear vibrations of coupled fluid‐structure systems when the fluid is described by its pressure filed. First the completeness of the eigenvectors is verified.

FE/FMBE coupling to model fluid–structure interaction
International Journal for Numerical Methods in Engineering, 2008AbstractIn this paper, a finite element (FE)/fast multipole boundary element (FMBE)‐coupling method is presented for modeling fluid–structure interaction problems numerically. Vibrating structures are assumed to consist of elastic or sound absorbing materials. An FE method (FEM) is used for this part of the solution.

Numerical simulation of fluid-structure coupled problems
2012This paper briefly describes the numerical models for the simulation of fluid-structure coupled problems. The applied models are primarily intended to simulate the fluid-structure dynamic interaction in seismic conditions. Models can simulate the most important non-linear effects of plane and spatial structures that are in direct contact with fluid ...
