| Abstract |
The course-keeping problem of a ship model in confined waterways is investigated by numerical simulations coupled with a control algorithm in the present study. The URANS method is applied to simulate viscous flows around the ship, and the overset mesh technique combined with the PD algorithm is adopted to realize the rudder action during course keeping. To improve simulation efficiency, the body-force propeller is applied and a virtual bank method is developed to simplify the modeling of bank effects. The results of free-running simulations indicate that the bank-induced yaw moment is the dominant factor causing ship-bank collisions in confined waterways. Applying the controller in simulations, the ship successfully achieves course keeping with either initial off-centerline deviation or heading angle. Furthermore, the simulated flow field indicates that the ship deviates a small distance from the waterway centerline during course keeping to overcome the additional sway force and yaw moment induced by propeller-rudder interaction. |
