A chapter in High Performance Computing in Science and Engineering '08, 2009, pp 411-424 from Springer

Abstract: Summary In this article two examples for applications in high-performance computing are presented. One is the fluid-structure interaction (FSI) in a tidal turbine. The other one is the simulation of unsteady vortices in hydraulic turbine draft tubes. The architecture for fluid-structure interaction with the in-house CFD code FENFLOSS and a commercial structural code is presented. Furthermore, issues of installing the environment on a NEC SX-8 vector computer is discussed and performance data is presented. Additionally, the issues of turbulence and the impact of turbulence models on the accuracy of the vortex capturing are investigated. All simulations are performed on a cluster (structural mechanics) and a NEC SX-8 vector computer (CFD).
