Abstract
The main objective of this study is to examine the characteristics of the rudder inflow (propeller slipstream) using FLUENT v.6 visualization technique. The rotating propeller of 5 blades and semi-spade rudder were set in a uniform flow condition. The rudder distorts the angle of attack (AoA) or incident angle to the leading edge of the rudder blade. Time-averaged pressure and velocity field are proposed to analyse the AoA and show similar AoA values of 0–7° at the region on rudder. However, it increases to 20° by those effects as the inflow comes to the rudder. From the AoA analysis, the similar flow pattern is found to be about 7° in terms of the rudder angle. Cautious access is additionally necessary to introduce a reasonable safety against those inflow phenomena that would significantly influence the durability of the rudder.
