Investigation of The Effect Hullvane and Bow Foil on Flat-Hull Ship Using CFD Approach

The flat-hull ship design is an innovative concept that saves costs and speed-up the fabrication of ship. Even though was hydrodynamically inefficient, some shipowners probably experienced issue with its unusual shape disadvantages where drag greater than conventional ships. This paper aimed to improve a vessel using hull vane bow foil reduce resistance. asymmetric NACA 4412 0012 were used for vane. For foil, only used. In addition, angle strut varied find out effect study performed in numerical approach computational fluid dynamics (CFD). mesh-based CFD RANSE solver this study, analysis will be conducted determine resistance ships hull-vane foil. It found effectiveness vanes on failed flat-hulled vessels. Because addition WSA ship, total increases following installation As alternative, can at Fn 0.44 0.59 by 10% 24%, respectively .
