Fluid structure interactions applied to downwind yacht sails

摘要

Sail analysis is a rapidly evolving field, since it has a big impact in the performances of yachts. In the present approach, a weak coupling in Arbitrary Lagrangian Eulerian (ALE) configuration has been chosen. The flow is analyzed with a Reynolds Averaged Navier Stokes (RANS) Finite Volume (FV) solver with turbulence models, whereas the structural analysis is performed with non-linear MITC Shell Finite Elements (FE). The approach and examples are presented and discussed with regards to a two dimensional downwind sail section in turbulent flow.
