초록
Fins are widely used for roll stabilization of passenger ferries and high performance naval ships, among others. In the present study, numerical simulations are performed to investigate the influence of end-plates upon the cavitation characteristics of a stabilizer fin for various angles of attack and speeds and the results are verified through a series of model experiments. It is found that a considerable retardation in tip vortex cavitation can be achieved with attachment of end-plates at the tip of the stabilizer fin. The results can be utilized for the design of stabilizer fins as well as the development of high performance control devices for ships.
