... work, we have considered the fluid–structure interaction problem of two coaxial cylinders, separated by a viscous Newtonian fluid and imposed small-amplitude harmonic beam vibrations. A new theoretical approach based on the Helmholtz expansion of the fluid velocity vector is carried out, leading...

... the primary circuit, with a characteristic velocity of 15 m/s in the middle part. Here, we consider the fluid–structure interaction problem corresponding to the particular configuration in which there is no axial flow but in which both the cylindrical fuel assembly and the guide tube vibrate. As the fuel...

... for characterizing the material properties of thick, pre-stressed elastic sheets via their fluid–structure interaction with a steady viscous fluid flow. Specifically, the hydrodynamic bulge test relies on a pressure drop measurement across a rectangular microchannel with a deformable top wall. We develop...

...Kenji Takizawa; Tyler Brummer; Tayfun E. Tezduyar; Peng R. Chen We present an extensive comparative study based on patient-specific fluid-structure interaction (FSI) modeling of cerebral aneurysms. We consider a total of ten cases, at three different locations, half of which ruptured. We use...

...E. H. van Brummelen; K. G. van der Zee; V. V. Garg; S. Prudhomme A crucial aspect in boundary-coupled problems, such as fluid-structure interaction, pertains to the evaluation of fluxes. In boundary-coupled problems, the flux evaluation appears implicitly in the formulation and consequently...

...Wen Peng; Zhaoyan Zhang; George Gogos; George Gazonas The dynamic response of a free-standing plate subjected to a blast wave is studied numerically to investigate the effects of fluid-structure interaction (FSI) in blast wave mitigation. Previous work on the FSI between a blast wave and a free...

...E. H. van Brummelen The subiteration method, which forms the basic iterative procedure for solving fluid-structure-interaction problems, is based on a partitioning of the fluid-structure system into a fluidic part and a structural part. In fluid-structure interaction, on short time scales the fluid...
