Due to the significant health and economic impact of blood vessel diseases on modern society, its analysis is becoming of increasing importance for the medical sciences. The complexity of the vascular system, its dynamics and material characteristics all make it an ideal candidate for analysis through fluid-structure interaction (FSI) simulations. FSI is a relatively new approach in numerical a...

Fluid-structure interaction simulation presents many computational difficulties, particularly when the densities of the fluid and structure are close. A previous report [20] has suggested that recasting the FSI problem in the context of optimal control may significantly reduce computation time. This report introduces a Neumann type control along with detailed analysis for the stability and exis...

For analyzing the flow field and topological structure of hemispherical parachute in low angles of attack, a fluid-structure interaction (FSI) simulation technique is established to decide the shape of the hemispherical parachute during terminal descent. In the fluid simulation, the semi-implicit method for pressure-linked equations consistent (SIMPLEC) algorithm is introduced to solve shear st...

We discuss in this thesis the numerical approximation of fluid-structure interaction (FSI) problems with a particular concern (albeit not exclusive) on hemodynamics applications. Firstly, we model the blood as an incompressible fluid and the artery wall as an elastic structure. To solve the coupled problem, we propose new semi-implicit algorithms based on inexact block-LU factorization of the l...

As a method to solve flow problems on complicated domains, an immersed boundary (IB) method equipped with the discrete forcing based on the fluid-structure interaction (FSI) is proposed in which the virtual interpolation points are introduced. The discrete force to the background fluid due to the no-slip condition on the surface of a fixed rigid boundary is the instantaneous amount of momentum ...

In this paper, we use a fluid–structure interaction (FSI) approach to simulate Coriolis mass flowmeter (CMF). The fluid dynamics is calculated by the open-source framework OpenLB, based on lattice Boltzmann method (LBM). For structural employ software Elmer, an implementation of finite element (FEM). A staggered coupling between two packages presented. mesh created generator Gmsh ensure complet...

The analytical approach, which lies at the basis of exact and natural sciences, rests on notion that complex systems can be reduced to simple components. This divide-and-conquer approach has shaped contemporary science technology, formed foundation for virtually all scientific breakthroughs in 19th 20th century. It is also origin separation mechanics into fluid solid mechanics, so much these br...

wind turbines are important devices that extract clean energy from wind flow. the efficiency of wind turbines should be examined under various working conditions in order to estimate off-design performance. numerous aerodynamic and structural research works have been carried out to compute aeroelastic effects on wind turbines. most of them suffer from either the simplicity of the modelling appr...

An important eld in computational science and engineering is the simulation of the coupled problem of uid ow interacting with a moving structure. A common notation for this is uid-structure interaction (FSI) problems, which include both aeroelasticity and hydroelasticity. Such multi-physics systems have received renewed attention as a result of the increase in length of slender structures e.g. ...

Fluid–structure interaction problems in general are often too complex to solve analytically and so they have to be analyzed by means of experiments or numerical simulation. Studying these phenomena requires modeling of both fluid and structure. Many approaches in computational aero elasticity seek to synthesize independent computational approaches for the aerodynamic and the structural dynamic ...
