“…In the simulation geometry settings, the design geometry of the draft ship must be in the form of solid bodies. The design geometry and boundary conditions used as space boundaries in the simulation process are shown in In determining the multiphase model, there are three types of multiphase modeling in Ansys US software (Ansys, 2020), namely Eularian, VoF, and Mixture. VoF modeling of two phases with a special free surface by tracing the grid mesh that has been made.…”

Fast patrol boats are designed for high performance in surveillance and warfare missions. In terms of hull technology development, the fast patrol boat commonly uses a V-type hull with hard chine. A duct vane is an innovation developed to improve the performance of patrol boats by combining the principles of wake-equalizing duct and hydrofoil. The objective of this paper is to investigate the hydrodynamic effect of the application of duct vane on the patrol boat hull design. The investigation was carried out using computational fluid dynamics that was validated using experiment data. The result of the duct vane application can improve the ship speed performance and reduce the total resistance by 40% at Fn 0.6. The results of this study also provide an overview of the influence of the duct vane on the lift force of a hard chine hull-type.
