Validation and Verification of Seakeeping in OpenFOAM

In this paper a detailed validation and verification of seakeeping simulations using Computational Fluid Dynamics (CFD) software OpenFOAM is presented. For the DSYHS #44 sailing boat, different head wave conditions for a fixed Froude number are simulated and the results are compared to experimental data. For the KRISO Container Ship (KCS), a large number of incident wave cases is considered at design Froude number. Incident wave parameters and direction of wave propagation with respect to ship’s heading are varied. The results for the total resistance, heave, pitch and roll are compared to experimental data. All simulations are conducted on three different grids in order to assess numerical uncertainties.
