| description | The development of high-speed craft technology for both the commercial sector and the military has grown rapidly in recent times. Optimizing recent inventions is one step toward realizing advanced ship technology. An element that affects efficiency is the effect on the hydrodynamics of the ship by the addition of a stern foil. A stern foil is an underwater hydrofoil that is mounted on the back of a ship to produce lift and additional thrust when the ship is in motion, impacting the trim and wet surface area of the ship and thus reducing drag. This study aims to determine the effect of the angle of attack configuration of a stern foil experimenting with a one-meter ship model at varying angles of attack: 0°, 1°, 2°, and 5°, using the computational fluid dynamic method. The results of this study indicate that the use of a specific stern foil configuration is effective in reducing the drag of the ship by 9%–26% in the Froude number range 0.5–0.75. |
