摘要

The present work is devoted to simulation of fluid-structure interaction and flow-induced vibration problems by using a partitioned procedure. A finite element structure solver is coupled with a finite volume fluid solver. A coupling interface has been developed for grid interpolation and scheme coupling control. An alternative mesh motion to a classical ALE formulation is proposed for the fluid computation and the method is validated by means of a test-case involving a pipe conveying fluid.
