Manoeuvring simulations using the overset grid technology in foam-extend
Full scale turning circle manoeuvre is simulated using the Finite Volume (FV) based CFD software called the Naval Hydro Pack, which is based on foam-extend. Results are directly compared to sea trial measurements for two propeller rotation rates. Two different approaches for modelling the free surface are investigated: as single–phase flow model with a simplified linearised free surface method, and a two–phase numerical model with Volume of Fluid (VOF) method for interface capturing. The comparison in terms of accuracy, computational time and robustness between the two methods is presented. In both approaches the propeller is modelled using the actuator disc model, while the moving rudder is handled using the overset grid technology. A newly developed publicly available open–source overset library based on foam-extend is used.
