This paper presents the optimization of vibrations of centrifugal pump considering fluid-structure interaction (FSI). A set of centrifugal pumps with various blade shapes were studied using FSI method, in order to investigate the transient vibration performance. The Kriging model, based on the results of the FSI simulations, was established to approximate the relationship between the geometrica...

SUMMARY An immersed finite element Fluid-Structure Interaction (FSI) algorithm with an anisotropic remeshing strategy for thin rigid structures is presented in two-dimensions. The algorithm consists in remeshing only the fluid elements that are cut by the solid such that they fit the solid geometry. This approach allows to keep the initially provided fluid mesh vertexes fixed during the whole s...

This work presents recent advances in visualizing multi-physics, fluid-structure interaction (FSI) phenomena in cerebral aneurysms. Realistic FSI simulations produce very large and complex data sets, yielding the need for parallel data processing and visualization. Here we present our efforts to develop an interactive visualization tool which enables the visualization of such FSI simulation dat...

Computational Structural Dynamics (CSD) simulations, Computational Fluid Dynamics (CFD) simulation, and Fluid Structure Interaction (FSI) simulations were carried out in an anatomically realistic model of a saccular cerebral aneurysm with the objective of quantifying the effects of type of simulation on principal fluid and solid mechanics results. Eight CSD simulations, one CFD simulation, and ...

A numerical investigation of the dynamic Fluid Structure Interaction (FSI) of a yacht sail plan submitted to harmonic pitching is presented to address both issues of aerodynamic unsteadiness and structural deformation. The FSI model — Vortex Lattice Method fluid model and Finite Element structure model — has been validated with full-scale measurements. It is shown that the dynamic behaviour of ...

Aeroelastic simulations of a 2.3 MW wind turbine rotor operating in different complex atmospheric flows are conducted using high fidelity fluid–structure interaction (FSI) simulations. Simpler blade element momentum (BEM) theory based likewise for comparison, and measurements from field experiments used validation the Good agreement is seen between simulated measured forces. It found that flows...

1. The first type of noise excitation originates from time varying forces acting on solids. These forces provoke mechanic vibrations (structure bound sound) within the solid parts which propagate until the outer surface of the bodies. At this outer boundary the vibrations are partly transferred to the adjacent fluid as a result of a fluid-structure-interaction (FSI). 2. The second type of noise...

Parallel overlapping Schwarz preconditioners are considered and applied to the structural block in monolithic fluid-structure interaction (FSI). The two-level overlapping Schwarz method uses a coarse level based on energy minimizing functions. Linear elastic as well as nonlinear, anisotropic hyperelastic structural models are considered in an FSI problem of a pressure wave in a tube. Using our ...
