Numerical Study on Wave Dissipation Performance of OWC-Perforated Floating Breakwater under Irregular Waves

This paper utilizes ANSYS-AQWA hydrodynamic simulation analysis software (2022 R2) to investigate the wave dissipation performance of an Oscillating Water Column (OWC) perforated floating breakwater under irregular conditions. The study examines effect spacing, width OWC opening, water depth, incident angle, and significant height on breakwater. results indicate that OWC-perforated surpasses similar structures. transmission coefficient is significantly influenced by spacing depth when subjected waves. opening also affects some extent, with wider openings demonstrating improved in case long-period angle 0 degrees yields enhanced performance. Although meaningful has minimal impact dissipation, it increases proportionally rise height. offers valuable insights for design implementation breakwaters holds practical implications research integrated devices combining power generation.
