Numerical approximation of fluid-structure interaction problem in a closing channel near the stability boundary
Original language description
This contribution deals with the numerical simulation of a fluid-structure interaction problem. The elastic body is modelled with the aid of a linear elasticity model. The fluid flow is described by the incompressible Navier-Stokes equations in the arbitrary Lagrangian-Eulerian formulation. The coupling conditions are specified and the coupled problem is formulated. The fluid-structure interaction problem is discretized by the finite element method solver applied both to the elastic part as well as to the fluid flow approximation. For the fluid flow approximation the residual based stabilization is used. Special attention is paid to the penalization boundary condition used at the inlet. It allows to relax an exact value of the inlet velocity on the boundary during channel closing phase nearly to complete channel closure. Numerical results for flow-induced vibrations near the stability boundary are presented and the critical velocity of flutter instability is determined.
