Abstract

In response to the high maneuverability demands of kelp harvesting vessels during row-changing operations, this study employs a screw propeller instead of traditional propellers as the propulsion device. To ensure that the screw propeller meets the requirements for kelp harvesting vessels, the study investigates the influence of structural parameters of the screw propeller on its propulsion performance. Using computational fluid dynamics (CFD) in combination with orthogonal experimental design, this study systematically investigates the effects of structural parameters on the hydrodynamic performance of the marine screw propeller. By analyzing the impact mechanisms of four factors—blade height (175–250 mm), lead (430–580 mm), number of helices (1–3), and number of turns (1–4)—on propulsion efficiency, the significance of each parameter is ranked as follows: number of helices > blade height > lead > number of turns. The optimal parameter combination is found to be a blade height of 450 mm, a lead of 430 mm, and a single-turn, single-helix structure, resulting in a propulsion efficiency of 27.26%. The findings provide a theoretical basis for the engineering optimization of marine screw propellers.
