THE CHARACTERISTICS OF STERN FLOW AND PROPULSION PERFORMANCE OF AN ASYMMETRIC STERN SHIP

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