Unsteady RANS CFD simulations of ship maneuverability in waves
It is important to be able to predict maneuvering performances of a ship in a real seaway since it is intimately related to the safety of ship operation at sea. Estimating ship maneuver in waves is a complex hydrodynamic problem because of the interactions of many factors such as ship resistance, seakeeping and maneuverability. The key objective of this project is to carry out a fully nonlinear unsteady RANS simulation to predict the ship seakeeping and maneuvering characteristics of a vessel in different waves. Dynamic overset grid method is introduced with the purpose of resolving large ship motion and rudder movement. Course keeping and maneuvering control module based on feedback control system is developed to control rudder movement according to standard maneuver mechanism. The simulation results are compared with available experimental data and are found to be in good agreement with the experiments, which demonstrates that CFD can be a reliable approach to estimate ship maneuverability in waves.
