Paper presented at the The 34th International Ocean and Polar Engineering Conference, June 16–21, 2024
Paper Number: ISOPE-I-24-587
... the wake flow at the stern is much more uniform and less rotational energy can be recovered. In this case, a more precise control of the design parameters of ESD (for instance, the angular position and the attack angle of the pre-swirl stators for the kind of ESD that aims at recovering rotational energy...

Paper Number: ISOPE-I-19-477
... superior propulsion performance and low noise performance. The PJP is composed of rotors, stators and a duct which covers the rotor and the stator. The rotor can produce the required thrust by interacting with the inflow as similar to the propeller blades. The stator is a set of blades with a certain angle...

Paper Number: ISOPE-I-13-520
... addresses the design of shaft bracket for a twin-screw vessel with stock propellers by potential flow theory. To investigate the viscous effects of the shaft bracket on flows, the stator drag and pre-swirl velocity on the disk plane are calculated by ANSYS Fluent. Finally, experiments are conducted...

... drive system, the difficulties increase. High normal forces exert a strong attractive clamping force between the stator and translator that the machines bearings must react against. The normal forces are 10 to 20 times higher than the generators shear forces. The design of novel fluid film linear...

... powers. An extremely large dc electric current must flow between the tips of rotors which are moving at high speed and stator surfaces which are at rest. A liquid metal in the small radial gap between the rotor tip and the concentric stator surface provides an ideal electrical contact because of its...
