| Outline of Final Research Achievements |
This study investigated characteristics of the viscous damping forces acting on wave energy converters. The viscous damping forces were measured and calculated by the model test and computational fluid dynamics to reveal characteristics of the forces, and The Regression formula based on the results measured and calculated was proposed. Numerical simulation considering viscous effects was developed. Effects of viscous damping forces on output power of wave energy converters was investigated.
