2025 Maritime Drag Reduction Workshop

JAN

2025

Description

(Detailed program has been updated below!!) 
In line with global efforts to decarbonize the shipping industry, there has been a concerted attempt to develop green shipping corridors and its relevant technologies. An important aspect of such initiatives is to establish methods/approaches for reducing the overall drag on a ship hull, with the goal of improving overall efficiency, thereby lowering emissions. The 2025 Maritime Drag Reduction Workshop aims to gather experts in the region to share their respective expertise, and to update the community on the state-of-the-art.

Jointly organized by the United States Office of Naval Research (ONR) Global in partnership with the Department of Mechanical Engineering at the National University of Singapore (NUS), and supported by The Theoretical and Applied Mechanics Society (Singapore), this two-day workshop focuses on the following basic research themes, with an emphasis on both modeling and experimental approaches for reducing drag: 
· Flow control in the liquid phase; 
· Liquid-structure interactions; 
· Artificial intelligence / machine learning; 
· Geometric shaping (e.g. riblets, dimples); 
· Novel materials (e.g. superhydrophobic
coatings); 
· Air lubrication; 
· Active methods for liquid forcing (e.g.
Lorentz forcing); 
· Diagnostics for drag quantification 
The organizing committee hopes to identify critical science and technology gaps through this workshop and develop a path forward for addressing these gaps.
