We present a high-order accurate scheme for fluid-structure interaction (FSI) simulations of flapping flight. The compressible Navier-Stokes equations are discretized using a discontinuous Galerkin arbitrary Lagrangian-Eulerian (DG-ALE) method on an unstructured tetrahedral mesh, and a wing-like structure, represented as a neo-Hookean material, is discretized using standard continuous Galerkin ...

A temporal homogenization approach for the numerical simulation of atherosclerotic plaque growth is extended to fully coupled fluid-structure interaction (FSI) simulations. The results indicate that two-scale yields significantly different compared a simple heuristic averaging, where only stationary long-scale FSI problems are solved, confirming importance incorporating stress variations on sma...

Fluid–structure interaction (FSI) analysis is often highly computationally expensive, making it infeasible to conduct iterative aeroelastic design studies or rigorous optimizations. This work develops a new method for that can be more efficient in the determination of final structure/fluid equilibrium configurations, especially during where attributes structure may altered but those flow are un...

We recently demonstrated the reduction of unified continuum and variational multiscale formulation to a computationally efficient fluid-structure interaction (FSI) via three modeling assumptions pertaining vascular wall. Similar coupled momentum method introduced by Figueroa et al., resulting semi-discrete yields monolithically FSI system posed in an Eulerian frame reference with only minor mod...

BACKGROUND Abdominal aortic aneurysm (AAA) is a dilatation of the aortic wall, which can rupture, if left untreated. Previous work has shown that, maximum diameter is not a reliable determinant of AAA rupture. However, it is currently the most widely accepted indicator. Wall stress may be a better indicator and promising patient specific results from structural models using static pressure, hav...

The integration and application of a new multi-objective tabu search optimization algorithm for Fluid Structure Interaction (FSI) problems are presented. The aim is to enhance the computational design process for real world applications and to achieve higher performance of the whole system for the four considered objectives. The described system combines the optimizer with a well established FS...

many diseases are related to cerebrospinal .uid (csf) hydrodynamics. therefore, understanding the hydrodynamics of csf .ow and intracranial pressure is helpful for obtaining deeper knowledge of pathological processes and providing better treatments. furthermore, engineering a reliable computational method is promising approach for fabricating in vitro models which is essential for inventing gen...

Nowadays, advanced composite materials such as carbon fiber reinforced plastics (CFRP) are being applied to many aircraft structures in order to improve performance and reduce weight. Most composites have strong, stiff fibres in a matrix which is weaker and less stiff. However, aircraft wings can break due to Fluid-Structure Interaction (FSI) oscillations or material fatigue. Material inspectio...

The article investigates the numeric simulation of two-way aeroelastic processes applied to the experimental phase of a compressor; physical, mathematical, rigid and grid models of the system “gas – rotor – stator” have been worked out; 2 FSI (two-way Fluid-Structure Interaction) calculations have been performed on the evaluation of the interaction between a gas-dynamic flow and a deformable ro...
