<p>This research investigates the hydrodynamic performance of two marine propellers, Wageningen B3-45-070 and Loop, through Computational Fluid Dynamics (CFD) simulations using the ANSYS Fluent solver. The Wageningen B3-45-070 propeller is selected as a reference due to its extensively validated experimental data, ensuring reliable comparisons. Meanwhile, the Loop propeller, developed via reverse engineering, integrates an advanced blade design intended to optimize efficiency. The study evaluates open-water characteristics, focusing on thrust and torque coefficients, as well as overall efficiency. To ensure a standardized assessment, both propellers are analyzed under identical CFD conditions. The investigation follows two operational scenarios: Variable advance speed: The rotational speed (n) is kept constant while the advance speed (Va) changes. Variable rotational speed: The advance speed (Va) remains fixed, while the rotational speed (n) varies across three different values. Findings reveal that the Loop propeller consistently achieves higher efficiency than the Wageningen B3-45-070 across all test conditions, with improvements ranging between 0.27% and 12.31%. These results highlight the Loop propeller’s potential in enhancing marine propulsion efficiency, making it a strong candidate for next-generation propeller designs.</p>

摘要

This research investigates the hydrodynamic performance of two marine propellers, Wageningen B3-45-070 and Loop, through Computational Fluid Dynamics (CFD) simulations using the ANSYS Fluent solver. The Wageningen B3-45-070 propeller is selected as a reference due to its extensively validated experimental data, ensuring reliable comparisons. Meanwhile, the Loop propeller, developed via reverse engineering, integrates an advanced blade design intended to optimize efficiency. The study evaluates open-water characteristics, focusing on thrust and torque coefficients, as well as overall efficiency. To ensure a standardized assessment, both propellers are analyzed under identical CFD conditions. The investigation follows two operational scenarios: Variable advance speed: The rotational speed (n) is kept constant while the advance speed (Va) changes. Variable rotational speed: The advance speed (Va) remains fixed, while the rotational speed (n) varies across three different values. Findings reveal that the Loop propeller consistently achieves higher efficiency than the Wageningen B3-45-070 across all test conditions, with improvements ranging between 0.27% and 12.31%. These results highlight the Loop propeller’s potential in enhancing marine propulsion efficiency, making it a strong candidate for next-generation propeller designs.
