Marine Fluid Engineering Lab
Machine-translated · View original
A lab that explores, from the standpoint of flow, the propulsive performance that determines a ship's fuel efficiency.

AboutAbout the lab
Improving propulsive performance through the flow around ships
To improve ship propulsive performance, the Marine Fluid Engineering Lab studies the flow around ships, the flow created by propulsors, and the hydrodynamic forces acting on them.
With global warming, CO2 emissions from ships are being strictly limited, and fuel efficiency, that is, propulsive performance, is becoming more important.
The lab develops computational numerical methods and conducts model tests in a high-speed circulating water channel.
Main research themes include the development of energy-saving rudders, propeller cavitation and pressure fluctuations at the stern, and propeller shape optimization.
Key terms
- Propulsive performance
- Performance equivalent to a ship's fuel efficiency. It is closely related to a ship's operating costs
- High-speed circulating water channel
- An experimental facility that creates flow by circulating water in a closed conduit and measures the flow and forces around a fixed model ship
- Hydrodynamic shape optimization
- Determining better shapes for ships and propellers from the standpoint of fluid dynamics
ResearchResearch themes
The lab theoretically studies the flow around ships and the flow generated by propulsors, aiming to improve ship propulsive performance. It is a field that requires improving existing technologies and developing new ones, based on validation with experimental data and accumulated knowledge.
