Abstract
The objective of this study is to obtain numerical benchmark solutions for KVLCC2 at drift angle 0 deg. on a 305M points grid using both ARS and Delayed DES methods with quantitative verification and validation. The behavior of different numerical schemes and turbulence models on different grid resolutions are evaluated. Overall, differences between a TVD scheme and a hybrid 4 th order scheme is negligible on such a fine grid. ARS is less dependent on grid resolution than DES. Compared to RANS, DES improves the prediction of the total resistance and velocity distribution for most regions at the propeller plane; however, DES tends to over-predict the velocity near the symmetry plane and the Reynolds stresses at the propeller plane. The grid induced separation using DES model is resolved by the DDES model, but both show modeled stress depletion inside the boundary layer.
