Description:

Penggunaan ducted propeller dapat memberikan pengaruh terhadap gaya dorong yang dihasilkan pada sebuah kapal. Dengan adanya tabung yang penampangnya berbentuk foil yang mengelilingi propeller tersebut, dapat meningkatkan efisiensi propeller dan menghasilkan gaya dorong yang lebih besar dibandingkan dengan propeller biasa yang tidak menggunakan tabung. Penelitian ini bertujuan untuk mengetahui karakteristik aliran pada ducted propeller serta gaya dorong yang dihasilkan. Penelitian ini menggunakan software Ansys-CFX dengan konsep CFD (Computational Fluid Dynamics) untuk menganalisa besarnya gaya dorong yang dihasilkan ducted propeller. Dari hasil simulasi kedua model propeller didapatkan kenaikan gaya dorong sebesar 17% pada ducted propeller bila dibandingkan dengan propeller yang tidak menggunakan ducted, dimana hal ini bersesuaian dengan published data yang menunjukkan adanya peningkatan sebesar 15%.


Alt. Description

The usage of ducted propeller can influence the thrust generated on a ship, where the presence of a duct with a cross-shaped foil surrounding the propeller can improve propeller efficiency and generate greater thrust than propeller without duct. The aims of this study are to determine the flow characteristics of the ducted propeller and generated the thrust. This research uses Ansys-CFX software with CFD method (Computational Fluid Dynamics) to analyze the value of the thrust on ducted propeller. From the simulation results of both models, propeller thrust can be increased by about 17% in the ducted propeller when compared to the propeller without ducted, and this is in good agreement with published data which showed an increase of about 15%.
