Optimization in marine propulsion: a step towards efficiency and low noise

Jun 5, 2024 | 12:40 - 1:05 PM

Reducing the environmental footprint of ships means, nowadays, not only maintaining the highest possible energy efficiency but also reducing underwater radiated noise, which is seen by regulations as a pollutant such as any GHG. Since energy efficiency and low noise are contrasting objectives, and unconventional propulsors often represent the only possible answer to these requirements, optimization-based design approaches are becoming increasingly familiar to tackle with medium- and high-fidelity computational tools this complex design challenge. Based on a decade of experience, some results of the University of Genoa in the design of conventional and unconventional propellers and energy saving devices, using a combination of different tools will be presented to demonstrate, once more, the flexibility and reliability of such methodologies.
