Paper presented at the SNAME 15th Propeller and Shafting Symposium, September 25–26, 2018
Paper Number: SNAME-PSS-2018-11
... behind the ship, instead a slightly smaller diameter is often selected. We have used computational fluid dynamics (CFD) to study a 120m cargo vessel with an integrated rudder bulb-propeller hubcap system and a 4-bladed propeller series, to increase our understanding of the hydrodynamic effects...

Paper presented at the SNAME 11th Propeller and Shafting Symposium, September 12–13, 2006
Paper Number: SNAME-PSS-2006-02
... In the present study an experimental analysis of the propeller-rudder interaction has been performed in a cavitation tunnel. The experiments simulated the condition of a rudder operation aft of a propeller but without the influence of the hull. The activity has been performed through...

Paper presented at the SNAME 10th Propeller and Shafting Symposium, September 17–18, 2003
Paper Number: SNAME-PSS-2003-05
... Various computational methods that have been developed in the past are combined in this paper to predict: (a) the performance of podded propulsors, and (b) the sheet cavitation on a rudder which is subject to the flow of an upstream propeller. An 3-D Euler-based finite volume method (GBFLOW-3D...

Paper presented at the SNAME 7th Propeller and Shafting Symposium, September 20–21, 1994
Paper Number: SNAME-PSS-1994-018
... A method for predicting rudder-propeller interaction is presented and compared with experimental measurements. A surface panel program (PALSUPAN) forms the basis of the analysis. The rudder and propeller are modelled separately using an iterative process whereby their respective interaction...

Paper presented at the SNAME 6th Propeller and Shafting Symposium, September 17–18, 1991
Paper Number: SNAME-PSS-1991-16
... During the past ten years, the world’s shipping business has been affected greatly by the increasing price of fuel. Energy-saving research has been increased in order to find ways of reducing operating costs of ships. Wake equalizing ducts. Grim wheels, rudder--balls added thrust fins. reaction...
