Abstract In this article, we derive an adjoint fluid-structure interaction (FSI) system in arbitrary Lagrangian-Eulerian (ALE) framework, based upon a one-field finite element method. A key feature of approach is that the interface condition automatically satisfied and problem size reduced since only solve for one velocity field both primary system. (and/or displacement)-matching optimisation c...

In this paper, the coupled weakly compressible (WC) and total Lagrangian (TL) smoothed particle hydrodynamics (SPH) model based on open-source multi-physics multi-resolution SPHinXsys library is used to simulate structural deformation failure problem in fluid-structure interaction (FSI). Aiming at that original TLSPH method could not cracks their propagation, fracture established, then verified...

Abdominal aortic aneurysm (AAA) rupture is the clinical manifestation of an induced force exceeding the resistance provided by the strength of the arterial wall. This force is most frequently assumed to be the product of a uniform luminal pressure acting along the diseased wall. However fluid dynamics is a known contributor to the pathogenesis of AAAs, and the dynamic interaction of blood flow ...

In this study, aeroelastic response and performance analyses have been conducted for a 5MW-Class composite wind turbine blade model. Advanced coupled numerical method based on computational fluid dynamics (CFD) and computational flexible multi-body dynamics (CFMBD) has been developed in order to investigate aeroelastic responses and performance characteristics of the rotating composite blade. R...

Growing horizontal axis wind turbines are increasingly exposed to significant sources of unsteadiness, such as tower shadowing, yawed or waked conditions and environmental effects. Due increased dimensions, the use steady tabulated airfoil coefficients determine airloads along long blades can be questioned in those numerical fluid models that do not have sufficient resolution solve explicitly d...

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...

1. The first type of noise excitation originates from time varying forces acting on solids. These forces provoke mechanic vibrations (structure bound sound) within the solid parts which propagate until the outer surface of the bodies. At this outer boundary the vibrations are partly transferred to the adjacent fluid as a result of a fluid-structure-interaction (FSI). 2. The second type of noise...

The kinematics and dynamics of the aortic valve (AV) are highly dependent on the combined mechanical properties of the valve and the aortic root (AR), as well as the blood flow. Previous numerical models of physiological AV and AR, that included coaptation under the full cardiac cycle, ignored the influence of the blood flow (performing “dry” simulations). This study presents a full fluid-struc...
