摘要：
Aiming to investigate the drag reduction performance of an antifouling shell rough surface, six different geometries of shell surface texture are simplified as V-shaped riblet, U-shaped riblet, space-V-shaped riblet, blunt-V-shaped riblet, L-shape driblet, and boolean AND-shaped riblet. Five kinds of riblets have the same geometric features: groove height and grooved spacing. SST-k-omega model is adopted for the turbulence model. The flow field structure above the different shaped riblet surfaces as well as shear stress and turbulent kinetic energy are analyzed. Moreover, how the flow is influenced by different shapes of riblets is discussed. The knowledge gained in this study can provide theoretical reference for optimal groove surface design of a ship hull with drag reduction performance.
