Outline of Final Research Achievements

A numerical code for 3D coupled analysis of fluid-structure interaction was developed based on the lattice Boltzmann method. The cross-flow displacements were compared among floating structures with circular, ellipsoidal, and square columns and it was found that the floater with square column has the minimum amplitude. It was also found that interaction between the vortex shed by the front column and the rear column suspend the vortex-induced motion. To validate these findings, single column and four columns were towed in the towing tank and the hydrodynamic force was measured.
