Fully reproducible RANS ship hydrodynamics for the JBC validation case

Abstract

. Simulation results are presented for a well established ship hydrodynamics validation case with the Japan Bulk Carrier (JBC). The results include the ship position, forces on the hull, water surface deformation and the stern flow. Simulation results are compared with measurements for all these quantities. The open source software OpenFOAM was employed, with finite volume numerics, RANS turbulence modelling, the volume-of-fluid method for the free surface, and ship motion functionality. In order to enhance the reproducibility of the results, the data files of the simulation case are made freely available. In combination with open source software, this allows for other research groups to re-simulate, modify and improve the case. Practical aspects of making this type of simulation data available are also discussed in the paper.
