Comparative Thermodynamic Analysis of Marine Propulsion Systems Under Varying Loads and Operational Conditions

Abstract

This study undertakes a meticulous examination of marine propulsion systems' efficiency and performance across diverse load scenarios and operational conditions. Through a comprehensive methodology encompassing energy and exergy analyses, comparative analysis methodologies, and detailed modeling and simulation using EBSILON Professional, this study uncovers crucial insights into the impact of load variations and operational conditions on propulsion system performance. This study reveals that there isn't a significant drop-off in system efficiency at 80% load when pressure relief valves are included across the system, indicating the effectiveness of these valves in maintaining performance under different operational scenarios.  By presenting and analyzing its findings, this project contributes valuable recommendations for optimizing marine propulsion systems, thereby enhancing their efficiency and sustainability in maritime operations.
