CNR Presents New Experimental Results on Leading-Edge Tubercles at AMT ’25

At the 8th International Conference on Advanced Model Measurement Technology for the Maritime Industry (AMT ’25), held on 29–31 October 2025 in Daejeon, Korea (https://www.amt2025.com), the National Research Council of Italy (CNR) presented new experimental findings on the effectiveness of leading-edge tubercles applied to naval propellers.

The presentation, delivered by Mario Felli (CNR-INM), showcased the results of extensive experimental campaigns carried out in CNR’s Large Cavitation Channel. Overall, the findings suggest that while leading-edge tubercles can locally modulate the flow and wake structure, their practical benefits for ducted propellers are strongly dependent on inflow conditions, propeller-duct combinations, and operational regime.

The talk generated significant interest within the international scientific community.
