We propose an Eulerian framework for modelling uid–structure interaction (FSI) of incompressible uids and elastic structures. The model is based on an Eulerian approach for describing structural dynamics. This is achieved by tracking the movement of the initial positions of all ‘material’ points. In this approach the displacement appears as a primary variable in an Eulerian framework. Our appro...

It is still difficult for traditional methods to simulate fluid-structure interaction (FSI) problems which are increasingly used to model cardiovascular system, and human organism. This contribution develops a new numerical method to analyze FSI, based on smoothed particle hydrodynamics (SPH). The Lagrangian and meshless characteristics of SPH presents distinct features to devise the method by ...

Atherosclerotic plaques may rupture without warning and cause acute cardiovascular syndromes such as heart attack and stroke. It is believed that mechanical forces play an important role in plaque progression and rupture. A three-dimensional (3D) MRI-based finite-element model with multicomponent plaque structure and fluid-structure interactions (FSI) is introduced to perform mechanical analysi...

Fluid-structure interaction (FSI) problems are of great interest, due to their applicability in science and engineering. However, the coupling between large fluid domains small moving solid walls presents numerous numerical difficulties and, some configurations, where thickness wall can be neglected, one consider membrane models, which derived from Koiter shell equations with a reduction comput...

A method is presented for studying and quantifying the biomechanical behavior of the human eye under elevated fluid and structural pressure loading. The approach taken involves a coupled synergistic computer modeling and experimental effort in which numerical models are used to predict the biomechanical response of eye under pressure, and physical cadaveric eye models along with appropriate ima...

In this research the exclusive decay of                         is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the  decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the decay. For this decay, via the exchange of mesons are chosen for the intermedi...

This work presents a full scale experimental study on the aero-elastic wind/sails/rig interaction in real navigation conditions with the aim to give an experimental validation of unsteady Fluid Structure Interaction (FSI) models applied to yacht sails. An inboard instrumentation system has been developed on a J80 yacht to simultaneously and dynamically measure the navigation parameters, yacht’s...

The study presents an experimental and numerical evaluation of bend-twist elastic coupling in composite passive-adaptive structures. Due to the lack of experimental validation in Fluid Structure Interaction (FSI) investigations, a full-field deformation of an aerofoil-shaped section under wind loading is measured. The experimental analysis is carried out at the University of Southampton 3.5 m ×...
