Background: The interaction between the blood and the vessel wall is of great clinical interest in studying cardiovascular diseases, the major causes of death in developed countries.Objective: To understand the effects of incorporating fluid-structure interaction into the simulation of blood flow through an anatomically realistic model of abdominal aorta and renal arteries reconstructed from CT...
In this article the subject fluid structure interaction is approached using a real and a computational model. Different scenarios are tested in a laboratory facility, where analysis of transient phenomena are created. Since it’s a fluid-structure elastic phenomenon, it’s important to study the phenomenon unsteady flow induced that reflects a structural vibration, developed when the steady-state...
In this work, we consider fluid-structure interaction simulation with nonlinear hyperelastic models in the solid part. We use a partitioned approach to deal with the coupled nonlinear fluid-structure interaction problems. We focus on handling the nonlinearity of the fluid and structure sub-problems, the nearincompressibility of materials, the stabilization of employed finite element discretizat...

Lateral nozzle forces are known to cause severe structural damage to any new rocket engine in development. Currently there is no fully coupled computational tool to analyze this fluid/structure interaction process. The objective of this study was to develop a fully coupled aeroelastic modeling capability to describe the fluid/structure interaction process during the transient nozzle operations....
In this paper, several models of structure-fluid coupling are employed to investigate on the vibration behavior of the structure. Using basic equations of vibration and employing a mathematical model, a single degree of freedom system is analyzed. Some parameters of the mathematical model are obtained from test. To examine structure-flow interaction, coupled system of nonlinear second-order dif...
An implicit scheme by partitioned procedures is proposed to solve a dynamic fluid–structure interaction problem in the case when structure displacements are limited rigid obstacle. For fluid equations (Sokes or Navier–Stokes), fictitious domain method with penalization was used. The equality of and velocities at interface obtained using technique. surface forces were computed solution domain. A...
