Numerical Solution of Fluid‐Structure Interaction Problems by Finite Element Method

In this paper the problem of the numerical approximation of a incompressible viscous fluid flow interacting with a flexible structure is considered. The problem is modelled with the aid of Reynolds equations together with k−ω turbulence model and structure motion is described by a system of ordinary differential equations. The problem is discretized in space by the Galerkin Least Squares stabilized FE method and the computational domain is treated with the aid of Arbitrary Lagrangian Eulerian method.
