An Experimental and Numerical Investigation on Hydrodynamic Characteristics of the Bow Thruster
Ocean Engineering, 2020Abstract While maneuvering or positioning in different situations, the hull, the angle of the inlet current, and the tunnel opening fairing onto the hull have serious impacts on the performance of the bow thruster. The co-operation of multiple bow thrusters affects each other in the hydrodynamic performance.

Operation Control for Improving Energy Efficiency of Shipboard Microgrid Including Bow Thrusters and Hybrid Energy Storages [PDF]
IEEE Transactions on Transportation Electrification, 2020 The frequent start/stop operation of a bow thruster presents a high pulsating power demand in shipboard microgrids while reducing the fuel efficiency of the diesel engines, which may induce potential instabilities.

Unbalanced Voltages of Bow Thruster Motor Performance in the Ship Using Simulation
International Review of Electrical Engineering, 2021The performance of the bow thruster motor depends on the quality of the supplied voltage and the voltage coming out of the motor. Under unbalanced voltage situation, it will cause the poor performance of the motor. The latest regulation of International Convention for the Prevention of Pollution from Ships (MARPOL) requires that the ship's electrical ...

Interaction between the ambient flow of a hull and bow-thruster inflow and outflow is examined theoretically and experimentally. Pressure distributions for duct inflow were derived by potential-flow techniques, and wind-tunnel pressure tests and flow-visualization experiments were conducted to determine the characteristics of duct outflow.

Design and Performance of Bow Thrusters
Marine Technology and SNAME News, 1972This paper concerns the hydrodynamic forces and moments produced by a bow thruster. Several broad problem areas are discussed and the extent of present-day knowledge indicated. These include general duct arrangement, duct shape, and impeller design. A step-by-step design procedure is outlined that permits the selection of a practical bow thruster. This
