Impact of hull propeller rudder interaction on ship powering assessment
Impact of hull propeller rudder interaction on ship powering assessment
It is the complex flow at the stern of a ship that controls the overall propulsive efficiency of the hull-propeller-rudder system. This work investigates the different analysis methodologies that can be applied for computing hull-propeller-rudder interaction. The sensitivity into which the interaction between the propeller and rudder downstream of a skeg is resolved as well as varying the length of the upstream skeg are also discussed including techniques to consider in such computations. Throughout the work, the importance of hull-propeller-rudder interaction for propulsive power enhancement is demonstrated. A final case study examines the performance of a twin skeg, twin screw arrangement.

Abstract
It is the complex flow at the stern of a ship that controls the overall propulsive efficiency of the hull-propeller-rudder system. This work investigates the different analysis methodologies that can be applied for computing hull-propeller-rudder interaction. The sensitivity into which the interaction between the propeller and rudder downstream of a skeg is resolved as well as varying the length of the upstream skeg are also discussed including techniques to consider in such computations. Throughout the work, the importance of hull-propeller-rudder interaction for propulsive power enhancement is demonstrated. A final case study examines the performance of a twin skeg, twin screw arrangement.
