This paper presents the new experimental and computational data on the JBC (Japan Bulk Carrier) hull form at straight ahead condition and 8◦ drift angle obtained at Hamburg University of Technology. The experiments were conducted on a double-hull model in a wind tunnel using the PIV technique. Good agreement with the results of other institutions (OU, NMRI) for the straight ahead condition is attained. The simulations at straight course are performed employing two different hybrid approaches, which are compared to each other and to the experimental results in terms of integral and distributed flow quantities. The more reliable approach (SST-DDES - SST-based Delayed Detached Eddy Simulation) is selected for further simulation of the flow at pure drift condition. In all cases a good agreement between the experimental and numerical results for most quantities is observed. However, the numerically predicted TKE levels on fine meshes turn out to be too high compared to the experimentally obtained ones and are attributed to the deterioration of shielding properties of the DDES delay function on finer meshes.
