The The Effect of Sail Layout on Fishing Vessels Hydrodynamics in The North Coast of Java Using Computational Fluids Dynamic
The fisheries sector is one of the potential sectors that contribute to Indonesia's state income, but it has often been neglected. Almost all fishing boats still use diesel engines as the main power source to propel the boat. The use of this type of fuel has an impact on increasing the level of air pollution such as CO2, SO2, and NOX in the atmosphere. However, research to reduce ship pollution, especially the combination of propulsion system for fishing boats using engines and sails, is rarely carried out. This study aims to determine the hydrodynamic characteristics of fishing vessels on the north coast of Java due to the application of numerical variations in laying sails using Computational Fluids Dynamics (CFD). The numerical simulation results show that the placement of sails in each model variation results in a change in the fluid flow pattern from bow to stern which can contribute to fuel efficiency. From the comparison of the three models, the most effective placement of sails is at the bow of the ship.
