New ship hull modifications to slash fuel use
Researchers at MIT have demonstrated that wedge-shaped vortex generators attached to a ship's hull can reduce drag by up to 7.5%, which reduces overall ship emissions and fuel expenses. The paper, "Net Drag Reduction in High Block Coefficient Ships and Vehicles Using Vortex Generators," was presented at the Society of Naval Architects and Marine Engineers 2025 Maritime Convention in Norfolk, Virginia.
