Abstract:The lock-in and drag amplification phenomenon is studied in a flexible cantilever using a simplified fluid-structure interaction (FSI) algorithm. NavierStokes equations for incompressible flow have been solved in 2D in several transverse planes of the line-like structure. A fractional step scheme has been used to solve the fluid field. In each fluid plane, the displacements have been taken into account considering an Arbitrary Lagrangian Eulerian (ALE) approach. The stabilization of convection and diffusion te… Show more
