A Study on Reduced Wind Drag Acting on the Hull of a River Ship in Headwind by Using CFD

Le résumé fourni par la source

The aerodynamic performance of a ship plays a crucial role in determining its efficiency, safety, and economic viability. While traditional ship design has primarily focused on optimizing hull forms to minimize water resistance acting on the hull, recent research highlights the growing importance of aerodynamic performances and wind drag acting on the ships, especially for ships with large accommodation above the water surface. In this study, aerodynamic performances of a cargo river ship were investigated by using Computational of Fluid Dynamics (CFD). From the results of analysis aerodynamic performance and wind drag acting on the original ship, several accommodation shapes have proposed for the ship to improve aerodynamic performances and reduce wind drag. The results were found that proposed accommodation shape for the ship, proposed a bow cover, modifed hatch cover and accommodation, which makes small change the ship structure, but it can improve aerodynamic performances and drastically reduce wind drag acting on the ship. Study on reducing wind drag acting on the ship is leading to lower fuel consumption, saving energy and improving economic efficiency.
