Abstract

important constructions is the construction of propeller strut. The propeller strut is a support consisting of an arm and a bearing that is attached between the propeller shaft and the hull on the stern of the ship. In this study, a modification was made to the propeller strut construction with the cross-sectional shape of the terrain in such a way that it gave the shape of the cross-sectional profile of the National Advisory Committee of Aeronautics (NACA) and formed a solid cylinder. This alternative strut design is modeled and simulated using the CFD tool in the ANSYS CFX software so that the average velocity, streamline flow, and pressure on the strut are known. And expressions with optimization with the particle swarm optimization method. The results of this study found that the NACA profile 16-021 is the best and efficient profile among 2 other profiles..
