Description
Summary:Ship resistance and flow field of KVLCC2 (KRISO Very Large Crude Carrier 2) are studied experimentally and numerically. A systematic analysis of both experimental and numerical uncertainty is performed. The experiment focuses on resistance distribution along the hull, which is divided into three segments. A detailed experimental uncertainty analysis with bias and precision limits is investigated. The validation of numerical calculation is performed for four grid densities and two turbulence models: 'Shear-Stress Transport k-ω' (SST) and 'Explicit Algebraic Stress k-ω' model (EASM). The validation and verification show that the numerical results are reasonable and reliable. The numerical study shows that both turbulence models can give good prediction of resistance, ship's sinkage and trim, as well as flow field around the hull. Comparatively, the 'EASM' model has higher accuracy. The prediction of resistance on the aft segment confirms the superiority of anisotropic 'EASM' model, and shows that the present measurement data are a valuable test case for both numerical verification and turbulence model validation.
