Fluid-structure coupling - Extensions and improvements

35th Aerospace Sciences Meeting and Exhibit, 1997
The requirement to deal with arbitrarily complex fluid and structural models, geometries and discretization techniques, introduces a number of problems associated to the transfer of information between the coupled programs. We study the transfer of loads from the fluid to the solid, the transfer of deformations from the solid to the fluid and the ...

Fluid–structure coupling in valveless micropumps

Journal of Micromechanics and Microengineering, 2011
Valveless micropumps work on the principle that the reciprocal forcing of fluid by an actuator through diffuser/nozzle elements generates a rectified mean flow. The pump characteristics depend on the coupling between the fluid and structure. We analyze the characteristics of valveless micropumps by developing a coupled model for the area-averaged ...

Coupling strategies for biomedical fluid–structure interaction problems

International Journal for Numerical Methods in Biomedical Engineering, 2009
AbstractThe coupling of lightweight and often thin‐walled structures to fluids in an incompressible regime is a recurring theme in biomechanics. There are many fluid–structure interaction (FSI) solution schemes to address these kinds of problem, each one with its costs and benefits. Here, we attempt a comparison of the most important FSI schemes in the

Computational modeling of coupled fluid-structure systems with applications

Structural Engineering and Mechanics, 2008
This paper outlines the development of a computational model in order to analyze the dynamic behaviour of coupled fluid-structure systems such as a) liquid containers, b) a set of parallel or radial plates. In this work a hybrid fluid-solid element is developed, capable of simulating both membrane and bending effects of the plate.

Implicit fluid–structure coupling for simulation of cardiovascular problems

International Journal for Numerical Methods in Fluids, 2002
Abstract 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, 1972
Abstract 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, 2013
Fluid-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

Coupled Fluid-structure Interactions

2017
In 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

A MODAL METHOD FOR COUPLED FLUID-STRUCTURE INTERACTION ANALYSIS

Journal of Computational Acoustics, 2004
A 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 ...
