Abstract
This study investigates the hydrodynamic performance of three distributed propulsion configurations with distinct hull shapes. The influence of duct design and hull geometry on thrust, absorbed power, and the resulting thrust-to-power ratio is explored, and a computational fluid dynamics analysis is conducted with a focus on the relationship between the hull and propulsion system at a constant speed of 3 m/s. The results indicate that a pontoon-shaped hull with matching propulsion configuration yields optimal performance, with superior thrust-to-power ratios and hydrodynamic efficiency. In addition, a comprehensive design graph is presented, with the intention of aiding ship designers in selecting suiTable propulsion configurations for specific vessel types. The findings highlight the importance of integrating hydrodynamic and performance criteria into the design of distributed propulsion systems, and provide insights for the development of next-generation efficient inland vessels. Overall, the study provides practical guidelines for optimising distributed propulsion layouts in shallow-water vessel design.
