On power performance of small self-propelled cutter suction dredger |
| |
| Abstract: | This paper carries out numerical simulation of a self-propelled cutter suction dredger with ship-propeller system to ensure its power performance under harsh conditions. It discusses the effect of the size of channel at fore body of the ship on the resistance, and the impact of the shaft submergence depth on the hydrodynamic performance of the hull and the ducted propeller, and the propulsor is designed for optimized application. |
