非対称船尾船の船尾流場と推進性能について

抄録

The influence of the propeller suction on the flow field at the stern is investigated for a ship with asymmetric stern. The inflow rotation into propeller disk is shown to be considerably strengthened at the propeller suction from the velocity field measurement with and without propeller. This phenomenon is fairly well predicted by use of the proposed modified Huang et al.'s method. Based on the above, the discussion is made for the new self-propulsion analysis method applied for this kind of vessel, and also for the energy saving mechanism due to inflow rotation.
