Abstract
The main objective of present study is to examine the characteristics of the complex rudder inflow(propeller slipstream) against the rudder cavitation using visualization technique. The rotating propeller of 6 blades and the semi-spade rudder are set in a medium-size cavitaion tunnel with a uniform flow condition. The rudder distorts the angle-of-attack (AoA) or incident angle to the leading edge of the rudder blade. Several methods such as uniform stream line, time-averaged velocity field and locally sampled area are proposed to analyze the AoA and show similar AoA values of 5-7° at the region of no rudder and no propeller trailing vorticity effects. However, it increases to 20°by those effects as the inflow comes to the rudder. From the AoA analysis the cavitation durability is found to be about 7°in terms of the rudder angle. Cautious access is additionally necessary to introduce a reasonable safety against those cavitation phenomena that would significantly influence the durability of the movable part. ? 2012 Elsevier Ltd.
