Abstract

This paper presents detailed validation and verification study for the KCS in calm water conditions. Validation is performed by comparing the resistance, sinkage and trim with experimental data for six Froude numbers, while verification is performed for each case by assessing grid and iterative uncertainties. A single set of governing equations for water and air is used where jump conditions at the free surface are used to discretise discontinuous density and dynamic pressure fields. Volume of Fluid (VOF) method is used for interface capturing, and the k-omega SST model is used for turbulence modelling. Ship motion is solved with quaternion based six degrees-of-freedom (6 DOF) rigid body motion equations. The method is implemented in the Naval Hydro pack based on foam-extend, a community driven fork of OpenFOAM software.
