Structured grids are independently generated around hull and rudder, and domain connectivity information between the two blocks are calculated by in-house overset grid assembler UP_GRID also developed at NMRI. Rigorous validations are made both in model and full scale using available experimental data. In model scale, resistance and self propulsion coefficients are both well predicted by the present computation. Computational accuracy in nominal and total wake specifically at 12 o’clock and near the boss must be improved. In full scale, all the computational results and their validation against full scale measurement data indicate the importance of treatment of wall roughness. When the roughness is taken into consideration in full scale simulation, it contributes to improve computational accuracy in estimating propeller rotation speed and distribution of axial component of total wake in front of the propeller better than those of estimated without roughness.enhttp://rightsstatements.org/vocab/InC/1.0/Computational Fluid Dynamics (CFD)Full scaleOverset gridInformatikTechnikIngenieurwissenschaftenConference Paper10.15480/882.337110.15480/882.3371Fluiddynamik und Schiffstheorie M-8Other
