When designing a ship, it is important to estimate accurately the effects of propeller-rudder interaction, as the rudder behind a propeller and a ship has a great effect both on the propulsive and maneuvering performance. In order to both understand the physical phenomenon and validate the RANS solver SHIPFLOW, the interaction between a propeller and a rudder in open water is qualitatively and quantitatively predicted and validated against experimental data. Furthermore, the propeller slipstream deformation is illustrated and the regain of rotational losses by the rudder is estimated.

Nyckelord: open water propeller rudder interaction RANS
