The hydroelastic behavior of propellers has been a recurring topic in ship propulsion; seen at time as a possible cause for failures of propulsive systems and some other times as an opportunity for improving the performances of propellers as a noise and vibration sources, it often suffered from a...

The additional resistance due to roughness is studied by means of CFD simulations. The KVLCC2 hull at full-scale Reynolds number is considered as a test case. A wall function formulation is used to model the rough wall turbulent boundary layer, where the roughness function is based on data from...

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...

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...

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...

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...
