Overcoming added-mass instabilities for fluid-structure interaction

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...

Presenting a Modified SPH Algorithm for Numerical Studies of Fluid-Structure Interaction Problems

A modified Smoothed Particle Hydrodynamics (SPH) method is proposed for fluid-structure interaction (FSI) problems especially, in cases which FSI is combined with solid-rigid contacts. In current work, the modification of the utilized SPH concerns on removing the artificial viscosities and the artificial stresses (which such terms are commonly used to eliminate the effects of tensile and numeri...

A Strong Coupling Scheme for Fluid-structure Interaction Problems in Viscous Incompressible Flows

In the present paper an embedded-boundary formulation that is applicable to fluid structure interaction problems is presented. The Navier-Stokes equations for incompressible flow are solved on a fixed grid which is not aligned with the body. A corotational formulation is used to describe the dynamics of a body that moves through the fixed grid undergoing large-angle/large-displacement rigid bod...
