Comparison of Code Coupling Scheme for Simulation of Fluid Structure Problems

Numerical simulation of industrial multi-physic problems is still a challenge to overcome as it generally requires large computational resources and may involve code coupling with appropriate numerical methods making data transfer possible, quick and accurate. Numerical simulation of fluid structure interactions and particularly of flow-induced vibrations is one of these issues; it is investigated in the present paper. In the present work one focuses his attention on methods for numerical simulation of flow-induced vibrations of tubes and tube bundles in presence of still water or laminar flows. Fluid structure code coupling process is described and first results of validation are presented. Fluid and structure codes are presented in the first section. Numerical scheme for code coupling process are investigated in the second part. Finally results of test cases are discussed in the last section.
