Nonlinear Dynamical Analysis for Coupled Fluid-Structure Systems [PDF]

The present research concerns the numerical dynamical analysis in elasto-acoustics, taking into account the geometrical non-linearities induced by the large displacements/deformations of the structure and assuming the internal acoustic fluid occupying an internal cavity coupled to the structure to remain in a linear range of vibration.

Performance Optimization of Interacting Sails Through Fluid Structure Coupling

Innovation in High Performance Sailing Yachts 2010, 2010
In this paper, the problem of sailing yacht rig design has been addressed through the development of a computational framework based on viscous Computational Fluid Dynamic (CFD) modelling for the aerodynamic part and on a non linear structural modelling for the structure part. The Fluid Structure Interaction (FSI) coupling used is a loose coupling. The
