Initial numerical propeller rudder interaction studies to assist fuel efficient shipping
Initial numerical propeller rudder interaction studies to assist fuel efficient shipping
The importance of a rudder cannot be understated; although relatively small, the hydrodynamic forces and moments developed on it are essential in the assessment of the manoeuvring characteristics of a ship. Additionally, ship rudders are almost always placed downstream of the propeller so they can take advantage of the increased local velocity due to the presence of the propeller. The knowledge of the interaction effects between the rudder and the propeller is a focal aspect for the improvement of ship’s performance. Propeller and rudder are considered as a propulsion unit in which the former is an active device that generates the thrust to keep the ship on move and the latter a control surface that produces the transverse force to keep the ship on course (Kracht 1992). In this paper, a method for rapidly computing the flow field and integrated forces acting on a rudder in a propeller race is presented.

Abstract
The importance of a rudder cannot be understated; although relatively small, the hydrodynamic forces and moments developed on it are essential in the assessment of the manoeuvring characteristics of a ship. Additionally, ship rudders are almost always placed downstream of the propeller so they can take advantage of the increased local velocity due to the presence of the propeller. The knowledge of the interaction effects between the rudder and the propeller is a focal aspect for the improvement of ship’s performance. Propeller and rudder are considered as a propulsion unit in which the former is an active device that generates the thrust to keep the ship on move and the latter a control surface that produces the transverse force to keep the ship on course (Kracht 1992). In this paper, a method for rapidly computing the flow field and integrated forces acting on a rudder in a propeller race is presented.
