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...

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/...
