Abstract

Research on aerodynamic performance and reduced wind drag acting on hull and large windward areas of high superstructures, such as passenger ships, container ships, roll on - roll off car ferries, and other ships, remains essential marine transportation. In this study, the wind drag acting on a passenger ship's above water hull was computed using ANSYS-Fluent, a commercial Computational Fluid Dynamics (CFD) code. Using CFD, the wind drag components, friction viscous wind drag, and pressure viscous wind drag acting on the hull of the original passenger ship were investigated. Based on the pressure and velocity distributions around the hull, several new hull forms with different frontal accommodation shapes have been proposed to reduce wind drag and improve the aerodynamic performances of the ship. By comparing the CFD results, a new above water surface hull with reduced wind drag was indentified in this study.
