- •
A biomimetic leading-edge tubercle design is applied on a tidal turbine model.
- •
A systematic cavitation and noise test has been conducted in a cavitation tunnel.
- •
Tubercles trigger the cavitation onset earlier but control the cavitation area.
- •
Noise is strongly related to the cavitation and influenced by the tubercles.
- •
Cavitation and noise diagrams are provided as a benchmark data for future studies.
