Analysis Methods and Design Measures for the Reduction of Noise and Vibration Induced by Marine Propellers
The paper presents the ongoing work in the research project ProNoVi. The objective of the project is to improve the numerical and experimental methods for the prediction of noise and vibrations induced by a propeller operating behind ship hull in full-scale conditions. Based on the improved...
Thrust Losses and Dynamic Loads on a Ducted Pushing Thruster in Regular Waves
This paper presents the results of CFD investigations into the hydrodynamics of a ducted azimuth propulsor operating in regular waves. Numerical simulations are conducted to quantify thrust losses and load oscillations experienced by the propulsor in waves of different height and magnitude...
Design and Numerical and Experimental Investigation of Pre-Swirl Stators PSS
This paper describes a CFD based approach to the design of a Pre-Swirl Stator (PSS) to be used as Energy Saving Device (ESD) on a retrofit chemical tanker. The designed PSS is shown to deliver 4% power savings at vessel selfpropulsion condition through a relevant speed range in full scale. This...
Numerical analysis of azimuth propulsor performance in seaways: Influence of oblique inflow and free surface
In the present work, a generic ducted azimuth propulsor, which are frequently installed on a wide range of vessels, is subject to numerical investigation with the primary focus on performance deterioration and dynamic loads arising from the influence of oblique inflow and the presence of free...
Analysis of Dynamic Loads on Azimuthing Ducted Propulsor under Off-Design Operation Conditions
In the present study, the results of CFD simulations by the unsteady RANS method of the flow around a generic model of azimuthing ducted pushing thruster are presented and compared with the results of model tests. The calculations are performed with the propeller operating at the design pitch (P...
