Sažetak
In this paper RANS based CFD calm-water resistance and propulsion simulations of two benchmark cases (container ship KCS and bulk carrier JBC) are presented. Two-phase flow is handled using the Volume-of-Fluid method, while the discontinuities at the free surface are resolved using the Ghost Fluid Method. Propeller is modeled using an idealized pressure-jump actuator disk model, allowing large time step size suitable for naval hydrodynamics with the preservation of accuracy and CPU time efficiency. Computations are performed with the Naval Hydro Pack developed in FV framework of foam-extend, a community driven fork of OpenFOAM. Model scale KCS resistance and wave pattern is evaluated with a detailed analysis of the bare hull wake field following ITTC recommendations. Self propulsion simulation is carried out for the JBC case comparing the global features of the flow with the experiment.
