Abstract:

With the increased interest in fuel saving technologies for ships, many kinds of energy saving devices (ESDs) have been developed and applied. Hi-Fin is a kind of energy saving device that has fin on the propeller boss cap which eliminates the hub vortex induced by propeller rotation as well as increases in propulsive efficiency. The aim of this study is to investigate the effects of Hi-Fin using computational fluid dynamics (CFD). To verify the results of numerical analysis, propeller wake fields were measured by stereoscopic particle image velocimetry (SPIV) and self-propulsion test has been performed in Hyundai Maritime Research Institute (HMRI). The result shows a good agreement between calculations and measurements in model scale.
