Abstract

Penelitian ini membahas perbandingan kinerja Gate Rudder dan Ducted propeller dalam meningkatkan efisiensi propulsi kapal menggunakan metode Computational Fluid Dynamics (CFD). Teknologi propulsi yang efisien sangat penting untuk mengurangi konsumsi energi kapal, dan dua sistem yang dibahas dalam penelitian ini adalah Gate Rudder, sistem kemudi ganda dengan profil asimetris yang mempercepat aliran fluida, serta Ducted Propeller, yang menggunakan nozzle untuk mengarahkan aliran air guna meningkatkan daya dorong. Simulasi dilakukan dengan menggunakan perangkat lunak ANSYS Fluent dan model turbulensi SST kω. Hasil menunjukkan bahwa Gate Rudder menghasilkan torsi dan daya dorong yang lebih tinggi dibandingkan Ducted Propeller, dengan peningkatan torsi sebesar 28% dan daya dorong sebesar 13%. Namun, Ducted propeller menunjukkan efisiensi yang lebih baik pada kondisi operasi tertentu, terutama pada variasi kecepatan rotasi yang lebih tinggi. Penelitian ini menekankan pentingnya memilih sistem propulsi yang sesuai dengan profil operasi kapal untuk mencapai efisiensi maksimal. Meskipun simulasi CFD memberikan wawasan penting mengenai performa kedua sistem, penelitian eksperimental lebih lanjut diperlukan untuk validasi hasil ini. Temuan penelitian ini berkontribusi dalam pengembangan teknologi propulsi yang lebih efisien, membantu optimasi kinerja kapal, serta mengurangi konsumsi bahan bakar di sektor maritim.

This research discusses the performance comparison between Gate Rudder and Ducted propeller in improving ship propulsion efficiency using Computational Fluid Dynamics (CFD) methods. Efficient propulsion technology is crucial for reducing ship energy consumption, and the two systems discussed in this study are the Gate Rudder, a dual rudder system with an asymmetrical profile that accelerates fluid flow, and the Ducted Propeller, which uses a nozzle to direct water flow and enhance thrust. The simulations were conducted using ANSYS Fluent software and the SST k-ω turbulence model. The results show that the Gate Rudder generates higher torque and thrust compared to the Ducted Propeller, with a 28% increase in torque and a 13% increase in thrust. However, the Ducted propeller demonstrated better efficiency under certain operating conditions, particularly at higher rotational speed variations. This research emphasizes the importance of selecting the appropriate propulsion system based on the ship's operational profile to achieve maximum efficiency. Although CFD simulations provide
valuable insights into the performance of both systems, further experimental research is needed to validate these results. The findings of this study contribute to the development of more efficient propulsion technologies, aiding in ship performance optimization and reducing fuel
consumption in the maritime sector.
