A space-time finite element formulation for fluid-structure interaction
We present a space-time finite element formulation of the Navier-Stokes equations which is stabilized via the Galerkin/least-squares approach. The variational equation is based on the time discontinuous Galerkin method and is written in terms of the physical entropy variables over the moving and deforming space-time slabs. The formulation thus becomes analogous to the classical arbitrary Lagran...
متن کاملRobust methods for fluid-structure interaction with stabilised finite elements
Various multifield problems and among them fluid-structure interaction applications arise in nearly all fields of engineering. The present work contributes to the development of a stable and robust approach for the numerical simulation of fluid-structure interaction problems. In particular two-dimensional and three-dimensional elastic structues interacting with incompressible flow are considere...
متن کاملAdvances in Space-Time Finite Element Methods for Structural Acoustics and Fluid-Solid Interaction
Traditional computational approaches toward simulation of radiation and scattering from elastic bodies submerged in an acoustic uid have been primarily based on frequency domain formulations. Classical time-harmonic approaches (including boundary element, nite element, and nite diierence methods) have been eeective for problems involving a limited number of frequencies (narrow band response) an...
متن کاملInvestigation of Fluid-structure Interaction by Explicit Central Finite Difference Methods
Fluid-structure interaction (FSI) occurs when the dynamic water hammer forces; cause vibrations in the pipe wall. FSI in pipe systems due to Poisson and junction coupling has been the center of attention in recent years. It causes fluctuations in pressure heads and vibrations in the pipe wall. The governing equations of this phenomenon include a system of first order hyperbolic partial differen...
متن کاملA Unified Finite Element Method for Fluid-Structure Interaction
In this article, we present a new unified finite element method (UFEM) for simulation of general Fluid-Structure interaction (FSI) which has the same generality and robustness as monolithic methods but is significantly more computationally efficient and easier to implement. Our proposed approach has similarities with classical immersed finite element methods (IFEMs), by approximating a single v...
