The rotordynamics and fluid dynamics of a turbo-machine considering the effect of fluid-solid interaction FSI are numerically investigated using finite element software ADINA. The iterative method is adopted in computation of coupled fields of displacement and fluid. What distinguishes the present study from previous ones is the use of ADINA’s rotational meshes and the FSI interface that separa...

We develop a numerical method for simulating coupled interactions of complex floating structures with large-scale ocean waves and atmospheric turbulence. We employ an efficient large-scale model to develop offshore wind and wave environmental conditions, which are then incorporated into a high resolution two-phase flow solver with fluid-structure interaction (FSI). The large-scale wind-wave int...

Pipe vibration induced by water hammer frequently emerges in conveyance system, especially the hydropower plant or pumped storage power station with long diversion pipelines. This turn affects hydraulic pulsation so that undesired fluid-structure interaction (FSI) arises. In this research, attention is given to a pipeline embedded concrete. A six-equation model was derived describe fluid-pipe-c...

This paper presents a fully coupled fluid-structure interaction (FSI) simulation model of soft pneumatic actuator (SPA). Previous research on modelling and SPAs mostly involves finite element (FEM), in which the fluid pressure is considered as load uniformly acting internal walls actuator. However, FEM does not capture physics flow inside an SPA. An accurate physical behaviour SPA requires two-...

Computational methods that make use of single one-way Fluid Structure Interaction (FSI) for modeling the Coriolis Mass Flowmeters' (CMFs) operations are prone to inaccuracies. These errors due their limitations in describing a fully coupled fluid structure interaction. The aim this study is produce CFD model CMF uses an iterative two-way coupling interaction accurately its performance. computat...

The rapid development of computing software has facilitated multifarious research in integrated circuit (IC) packaging. Complicated and complex processes can be visualized via simulation modeling with this software. The applications of aided software enhance the fundamental physicochemical understanding and visualization of the IC encapsulation process. In this article, fluid–structure interact...

PURPOSE This paper proposes a model to measure the cardiac output and stroke volume at different aortic stenosis severities using a fluid-structure interaction (FSI) simulation at rest and during exercise. METHODS The geometry of the aortic valve is generated using echocardiographic imaging. An Arbitrary Lagrangian-Eulerian mesh was generated in order to perform the FSI simulations. Pressure ...

This work presents new fluid-structure interaction (FSI) models in both 2D and 3D of the effect of using vascular stents as treatment of cerebral berry aneurysms. The stent is positioned inside the cerebral artery covering the neck of the aneurysm. The stent is expected to alter the blood flow into the aneurysm such that the blood coagulates due to low blood velocity, and rupture of the aneurys...

With increased interest in renewable energy, the power capacity of wind turbines is constantly increasing, which leads to rotor sizes. ever larger diameters, complex and non-linear fluid-structure interaction (FSI) effects on turbine aerodynamic performances become significant, can be fully studied using hi-fidelity 2-way FSI simulation. In this study, a two-way model developed implemented Open...
