| contents | <p>This study presents a comparative performance analysis of the jet and screw propulsion (JSP) systems, which<br>utilized mathematical and simulation-based models of the JSP systems analyses, compares the thrust generation<br>of JSP systems under varying speed conditions (from 5 m/s to 25 m/s) and analyzed the fuel efficiency of the JSP<br>systems across different operational scenarios The simulation incorporated hydrodynamic parameters such as<br>mass flow rate, jet velocity, propeller diameter, thrust coefficient, and fuel mass flow rate. Results show that while<br>both propulsion systems generated substantial thrust across all speed regimes, the screw propulsion system<br>consistently outperformed the jet system in thrust generation and efficiency. At the highest ship speed of 25 m/s,<br>the screw propulsion achieved a thrust of 29,343 N compared to 10,500 N for the jet system. The specific fuel<br>consumption (SFC) of the screw system ranged from 4.42 g/kN·s to 0.88 g/kN·s, markedly lower than the jet<br>system’s 48 g/kN·s to 9.6 g/kN·s, indicating approximately 11-fold greater fuel efficiency. Similarly, screw<br>propulsion maintained a consistently higher propulsive efficiency, while the jet system improved from 0.14 to<br>0.36 with increasing speed. The study concludes that screw propulsion provides superior thrust and fuel economy<br>across all tested speeds, making it better suited for general marine operations. In contrast, jet propulsion offers<br>advantages primarily in high-speed or specialized hydrodynamic applications. The research contributes to<br>propulsion performance literature by providing validated comparative metrics and highlighting efficiencystability relationships crucial for system selection and optimization in marine engineering.</p> |
