The kriso container ship (KCS) test case: an open source overview

Abstract

In this work, the analysis of the Kriso Container Ship (KCS) test case using the OpenFOA RANS solver is proposed. Both ship resistance in calm water, propeller open water performances, self-propulsion calculations are proposed and the numerical results are validated by a comparison with the model scale experiments shared in literature and through workshops. The analyses are carried out applying the open source tools, from pre- to post- processing, available in the OpenFOAM environment, namely snappyHexMesh for the generation of the computational mesh, simpleFoam, pimpleDyMFoam, LTSInterFoam for the solution of the various hydrodynamic problems and Paraview for the post-processing of the results. The comparison with the experimental measurements, finally, demonstrates the maturity of these solvers for a reliable and, from an engineering point of view, accurate prediction of some of the peculiar characteristics of the flow ships and propellers are subjected to.
