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 is c...

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 surfac...

This paper presents a numerical study of the ventilation phenomenon based on model tests of a pushing thruster with variable advance ratios at a constant immersion depth to radius ratio h/R=1.6. This study uses STAR-CCM+, a commercial CFD code which uses a VOF formulation (Volume Of Fluid) in order ...

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 (P0.7/...

The paper deals with the topic of monitoring the performances of a vessel in service in order to establish whether fouling of the hull have worsened the hydrodynamic efficiency of the ship. In the paper the aspects of acquisition, treatment and presentation of the data are discussed. Particular focu...

Effect of roughness on frictional resistance is investigated experimentally and numerically. Resistance tests are performed with several plates coated with different paints, which have different roughness. Front plate is 4 m long and aft plates are 6 m long resulting in a total hydrodynamic length o...
