Analysis of the Aerodynamic Performance of Circular and Conical Rotor Cylinders Considering Rotor Arrangements Using CFD
With the strengthening of greenhouse gas (GHG) regulations by the International Maritime Organization (IMO), Rotor Sails have attracted increasing attention as a wind-assisted propulsion technology for improving fuel efficiency and reducing carbon emissions in ships. This study investigates the aerodynamic performance of cylindrical and conical Rotor Sails for a 17,000 DWT multipurpose maritime demonstration vessel using computational fluid dynamics (CFD). Numerical simulations were performed using ANSYS Fluent with the k-ω SST turbulence model to evaluate the effects of the Spin Ratio (SR), end-plate diameter ratio, rotor geometry, and rotor arrangement on aerodynamic performance. The results indicate that both cylindrical and conical Rotor Sails achieved the highest aerodynamic efficiency at SR = 2, while the parallel (P) arrangement exhibited the lowest performance due to increased aerodynamic interference. These findings provide useful design guidelines for optimizing Rotor Sail geometry and arrangement and are expected to contribute to the practical application of wind-assisted propulsion systems for environmentally friendly ships.
