Analisa Performa Baling-Baling Pada Kapal Polbeng II Menggunakan Simulasi CFD

Abstract

Abstract

A propeller is a propulsor used to convert rotational motion into thrust by imparting momentum to a fluid. A three-blade propeller has three blades arranged at specific angles and shapes to optimize water flow. Each blade is designed to create effective thrust while minimizing turbulence and drag. The main advantage of this design is its ability to generate strong thrust while keeping noise and vibration levels low. This research explores the performance of the propeller, focusing on the analysis of thrust, torque, and efficiency produced under various propeller rotation conditions. Using a Computational Fluid Dynamics (CFD) approach, simulations were conducted to study the influence of propeller blade design and flow parameters on performance efficiency. The simulation results indicate that increasing the propeller rotation speed significantly affects the propeller characteristics, resulting in higher thrust and torque values, while the highest efficiency value of 0.0015 is observed at 400 RPM, with a decrease in efficiency if the rotation speed exceeds 400 RPM.
