Study on energy harvesting performance of flapping hydrofoil with sidewalls and pitching axis

Key Points

• Flapping hydrofoils significantly improve energy harvesting performance compared to fixed designs.
• The introduction of sidewalls increases efficiency by approximately 20% during testing under specific conditions.
• Observational analysis on flapping hydrofoils was conducted under varying pitch angles and flow conditions.
• Findings may enhance energy harvesting strategies, especially in aquatic environments.
