“…Thus, the setup is chosen in such a manner that the inflow velocity guarantees a "stable" oscillation of the flexible structure in the second mode with sufficient distance from the transition regime. As described in Kalmbach and Breuer [15] the measured inflow turbulence level is low (Tu inflow = 0.02). The flow parameters are summarized in Table 2.…”

“…For this purpose the inflow velocity of the channel u inflow was varied in a wide range up to about 2.5 m/s within the experimental investigation observing the resulting displacements and frequencies of the structure. As shown in Kalmbach and Breuer [15]. For low inflow velocities the flexible structure was found to deform in the first swiveling mode.…”

“…For the structure, the densities were measured and pure structural test cases were performed (see AppendixA) to evaluate the other material parameters (see Table 3). In [15] Young's modulus of the rubber was determined based on a purely structural static test case to E rubber = 3.15 MPa. In the present study a purely structural dynamic test case is carried out and leads to a different value of E rubber = 4.10 MPa.…”

“…The Reynolds number is still Re = 30,470. The entire experimental investigations of this test case denoted FSI-PfS-2a are presented in Kalmbach and Breuer [15]. The rear mass and the less stiff material also change completely the governing mechanism responsible for the deformations of the flexible structure.…”

The objective of this paper is to provide a detailed numerical investigation on the fluid-structure interaction (FSI) test case presented in Kalmbach and Breuer (Journal of Fluids and Structures, 42, (2013), pp. 369-387). It relies on detailed experimental investigations on the fluid flow and the structure deformation using modern optical measurement techniques such as particle-image velocimetry and laser triangulation sensors. The present numerical study is based on an efficient partitioned FSI coupling scheme especially developed for turbulent flow simulations around light-weight structures using large-eddy simulation. The current FSI configuration is composed of a fixed cylinder with a flexible thin rubber plate and a rear mass inducing a turbulent flow (Re = 30,470). Mainly based on a movement-induced excitation the flexible structure oscillates in the second swiveling mode involving large deformations. Thus, particular attention has been paid to the computational model and the numerical set-up. Special seven-parameters shell elements are applied to precisely model the flexible structure. Structural tests are carried out to approximate the optimal structural parameters. A fine and smooth fluid mesh has been generated in order to correctly predict the wide range of different flow structures presents near and behind the flexible rubber plate. A phase-averaging is applied to the numerical results obtained, so that they can be compared with the phase-averaged experimental data. Both are found to be in close agreement exhibiting a structure deformation in the second swiveling mode with similar frequencies and amplitudes. Finally, a sensitivity study is carried out to show the influence of different physical parameters (e.g. Young's modulus) and modeling aspects (e.g. subgrid-scale model) on the FSI phenomenon.

This paper details the validation of a non‐conforming arbitrary Lagrangian‐Eulerian fluid‐structure interaction technique using a recently developed experimental 3D fluid‐structure interaction benchmark problem. Numerical experiments for steady and transient test cases of the benchmark were conducted employing an inf‐sup stable and a general Galerkin scheme. The performance of both schemes is assessed. Spatial refinement with three mesh refinement levels and fluid domain truncation with two fluid domain lengths are studied as well as employing a sequence of increasing time step sizes for steady‐state cases. How quickly an approximate steady‐state or periodic steady‐state is reached is investigated and quantified based on error norm computations. Comparison of numerical results with experimental phase‐contrast magnetic resonance imaging data shows very good overall agreement including governing of flow patterns observed in the experiment.

In this paper a fluid‐structure interaction (FSI) experiment is presented. The aim of this experiment is to provide a challenging yet easy‐to‐setup FSI test case that addresses the need for rigorous testing of FSI algorithms and modeling frameworks. Steady‐state and periodic steady‐state test cases with constant and periodic inflow were established. Focus of the experiment is on biomedical engineering applications with flow being in the laminar regime with Reynolds numbers 1283 and 651. Flow and solid domains were defined using computer‐aided design (CAD) tools. The experimental design aimed at providing a straightforward boundary condition definition. Material parameters and mechanical response of a moderately viscous Newtonian fluid and a nonlinear incompressible solid were experimentally determined. A comprehensive data set was acquired by using magnetic resonance imaging to record the interaction between the fluid and the solid, quantifying flow and solid motion.
