Aerodynamic Load Prediction on a Patrol Vessel Using Computational Fluid Dynamics

Aerodynamic loads and moments on a naval patrol vessel are investigated using computational fluid dynamic simulations based the OpenFOAM solver. After initial turbulence, time, grid dependency study, model scale were performed for wide range of inflow angles to predict aerodynamic forces acting at different heading conditions. For validation, results compared with wind tunnel data similar hull forms. Finally, full-scale few cases investigate possible effects simulation results. The revealed effect turned out significant only yaw moment response. In this we aimed produce reliable load high-speed vessel, which is essential developing manoeuvring models. We conclude that Computational Fluid Dynamics capable providing predictions vessels sophisticated superstructures, in an economical manner.
