Innovation to Reduce Carbon Emissions in Shipping
At Adamant Global Alliance, we are utilizing science and technology to address the challenges of working toward clean shipping. This includes introducing innovative research to meet the rising restricting environmental regulations in the maritime industry, including the Energy Efficiency Existing Ship Index (EEXI) and Energy Efficiency Design Index (EEDI). These standards demand significant reductions in carbon emissions and improved energy efficiency in shipping.
To meet these evolving requirements, we are utilizing the Coanda effect fluid dynamics concepts to pioneer a novel approach to reducing energy consumption and promoting sustainable shipping.
Objective and Tools
Our research focuses on applying Coanda flow jets along the ship hull to generate a thin air sheet that isolates the hull, reducing the wetted surface area. This eventually creates a dry zone minimizing frictional resistance.
Utilizing high fidelity Computational Fluid Dynamics (CFD) simulations, we have achieved significant progress in understanding and optimizing this innovative concept. Volume of Fluid (VOF) and turbulence models were solved numerically to investigate the two-phase flow around the ship involving complex interactions between air, water, and the hull surface.
Ongoing Investigation and Improvements
While our initial findings are promising, we are actively refining the system through iterative research and development. Current investigations focus on optimizing jet configurations, pressure levels, and flow dynamics to maximize energy efficiency. These ongoing efforts are guided by rigorous scientific analysis, ensuring the system adaptability and effectiveness for a wide range of vessel types and operating conditions.
A technology breakthrough
This research represents a unique application of the Coanda effect in the maritime industry, offering a cost-effective solution to the challenges of decarbonization an area where recent methods haven’t shown a great potential yet. Unlike other energy saving devices such as traditional air lubrication systems, our approach minimizes retrofitting requirements while delivering substantial efficiency gains.
By integrating this technology into both new and existing vessels we support compliance with EEXI and EEDI benchmarks set by the International Maritime Organization (IMO).
