Abstract

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.

利用计算流体动力学研究风帆布局对爪哇岛北海岸渔船流体力学的影响
渔业部门是为印尼国家收入做出贡献的潜在部门之一,但却常常被忽视。几乎所有渔船仍然使用柴油发动机作为推动船只的主要动力源。这种燃料的使用会增加大气中的二氧化碳、二氧化硫和氮氧化物等空气污染。然而,减少船舶污染的研究,特别是渔船使用发动机和风帆组合推进系统的研究,却很少开展。本研究旨在利用计算流体动力学(CFD)确定爪哇岛北海岸渔船在铺设风帆时因数值变化而产生的水动力特性。数值模拟结果表明,每个模型变化中的风帆布置都会导致从船头到船尾的流体流动模式发生变化,从而有助于提高燃油效率。通过对三种模型的比较,最有效的船帆布置位置是船头。
