Advanced Flow Control Strategies for Drag Reduction in Fishing and Ferry Vessel Designs

This project focuses on advancing flow control strategies to improve the energy efficiency of fishing and ferry vessels, vital components of Nova Scotia’s maritime economy and transportation network. These vessels currently face significant challenges in reducing fuel consumption and greenhouse gas emissions, both of which are critical to achieving the province’s net-zero targets.

Using advanced computational fluid dynamics (CFD) simulations, the research will explore passive and active flow control techniques designed to minimize hydrodynamic drag. Passive strategies may include surface modifications like riblets or grooved textures, while active methods could involve devices such as vortex generators or air-layer systems. The project will examine how these technologies interact with water flow, identifying the optimal designs that enhance energy efficiency without compromising vessel performance.

The project’s objectives are to (1) develop innovative flow control solutions that achieve measurable reductions in drag, (2) provide cost-effective retrofit designs for existing vessels, and (3) create a design framework to guide future adoption of these strategies across Nova Scotia’s fishing and ferry fleets. The research will also assess the economic and operational feasibility of implementing these solutions at scale.

The anticipated outcomes include a reduction in fuel consumption and emissions for targeted vessels, improved operational efficiency, and practical design recommendations for industry stakeholders.

This work has the potential to significantly contribute to Nova Scotia’s transition to sustainable maritime practices, while maintaining the competitiveness of its vital fishing and ferry industries. By addressing both economic and environmental objectives, this project aligns closely with the goals of the Net Zero Emerging Concepts and Technologies Research Program.
