One-fluid formulation for fluid–structure interaction with free surface

A monolithic fluid-structure interaction formulation for solid and liquid membranes including free-surface contact

A unified fluid-structure interaction (FSI) formulation is presented for solid, liquid and mixed membranes. Nonlinear finite elements (FE) and the generalized-α scheme are used for the spatial and temporal discretization. The membrane discretization is based on curvilinear surface elements that can describe large deformations and rotations, and also provide a straightforward description for con...

Mathematical formulation of fluid-structure interaction problems

— In this article we study three different types of fluid-structure interaction problems. A gênerai mathematical framework is given and then we show how the gênerai results can be applied to the three spécifie problems ; evolutionary problems, as well as vibration (eigenvalue) problems are considered. Résumé. — Dans cet article nous étudions trois types différents de problèmes d'interaction flu...

BEM-FDM modeling of water free surface interaction with trapped air in OWC chamber for calculating generated power

Free surface modeling plays an important role in some ocean structures design, especially in Oscillating Water Column (OWC) devices. Boundary element method (BEM) is a suitable method for free surface modeling due to its simplicity, quick solving, and low data storage requirement. In this paper, BEM was used for free surface modeling in OWC chamber and out of it. Linear kinematic and dynamic bo...

A Fully Eulerian formulation for fluid-structure-interaction problems

In this work, we present a Fully Eulerian framework for fluid-structure interaction (fsi) problems coupling the incompressible Navier-Stokes equations with a hyperelastic solid. The Fully Eulerian framework is a monolithic implicit variational formulation for the coupled problem. In contrast to the well-established Arbitrary Lagrangian Eulerian (ALE) coordinates, the Fully Eulerian framework fo...
