Comparative Analysis of B-Series, Au-Outline Gawn Series and Kaplan Series Propeller on Trimaran Ship using Computational Fluid Dynamics Method

摘要

The propeller on a trimaran vessel requires some special criteria such as large thrust value, low-pressure value, and a smooth flow of propellers. This study has focused on the comparison of three types of propellers namely B-series, Au-Outline Gawn Series, and Kaplan series by considering some aspects of propeller diameter, number of blades, skew angle, and pitch. The numerical analysis was made by using Computational Fluid Dynamics (CFD) program to evaluate the performance of the propeller configurations. The result shows that Kaplan Series have the thrust value of 455628 N, the torque value of 96456.6 Nm, the pressure average value of 18608.92 Pa. According to the numerical results, it can be concluded that Kaplan series have a better performance compares with AU-Outline Gawn Series and B-Series for the Trimaran Ship.
