Interaction between an incompressible flow and elastic cantilevers of circular cross-section

In English

Författare

Summary, in English

The purpose of this work is to study the deformation of elastic cantilevers due to hydrodynamic forces by coupled fluid-structure interaction simulations. The cantilever is placed in a rectangular duct and the Reynolds number based on bulk velocity and cantilever diameter is 400. Reduced velocities in the range pi/4 to 2 pi are studied, which covers both un-synchronised motion and the initial branch of synchronisation. The cantilever surface is represented by a virtual boundary method which replaces a solid object in flow by additional force distribution to satisfy local boundary condition. The flow field is solved using a Cartesian finite difference code and the deformation of the cylinder a finite element approach using one-dimensional beam elements is used. (C) 2013 Elsevier Inc.
