Full-scale, 3D, time-dependent aerodynamics and fluid–structure interaction (FSI) simulations of a Darrieus-type vertical-axis wind turbine (VAWT) are presented. A structural model of the Windspire VAWT (Windspire energy, http://www.windspireenergy.com/) is developed, which makes use of the recently proposed rotation-free Kirchhoff–Love shell and beam/cable formulations. A moving-domain finite-...

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...

Added-mass instability is known to be an important issue in the partitioned approach for fluid-structure interaction (FSI) solvers. Despite the implementation of the implicit approach, convergence of solution can be difficult to achieve. Relaxation may be applied to improve this implicitness of the partitioned algorithm, but this commonly leads to a significant increase in computational time. T...

We evaluate a number of different finite-element approaches for fluid–structure (contact) interaction problems against data from physical experiments. This consists trajectories single particles falling through highly viscous fluid and rebounding off the bottom tank wall. The resulting flow is in transitional regime between creeping turbulent flows. type configuration particularly challenging n...

Abdominal aortic aneurysm (AAA) is a localized dilatation of the aortic wall. The lack of an accurate AAA rupture risk index remains an important problem in the clinical management of the disease. To accurately estimate AAA rupture risk, detailed information on patient specific wall stress distribution and aortic wall tissue yield stress is required. A complete fluid structure interaction (FSI)...

In this paper, we present a multi-resolution smoothed particle hydrodynamics (SPH) method for modeling fluid-structure interaction (FSI) problems. By introducing different smoothing lengths and time steps, the spatial-temporal discretization is applied with resolutions fluid structure. To ensure momentum conservation at coupling, position-based Verlet integration scheme introduced. Furthermore,...

Osteocytes are bone cells that can sense mechanical cues (stress and strain) respond by releasing biochemical signals direct remodeling. This process is called mechanotransduction which, in osteocytes, not well understood yet because vivo studies have proven difficult due to the complexity inaccessibility of flow–osteocyte lacuna-canaliculi system. While silico (modeling simulation) become powe...

Vortex-induced vibration (VIV) is a highly nonlinear fluid-structure interaction (FSI) phenomenon, and its accurate prediction remains challenging. In this study, we developed high-order partitioned FSI framework towards simulation of the VIV phenomenon. The focus on simulating two-way coupled between flexibly mounted rigid body surrounding fluids. framework, computational fluid dynamics method...
