Hydrodynamic loads must be accurately predicted to design robust control systems for Unmanned Underwater Vehicles (UUVs). Conventionally, these loads are estimated through either towing tank experiments (involving oblique frameworks, planar motion mechanisms, or rotating arm tests) or semi-empirical methods. With enhancements in high-performance computing capacities, the reliability of numerical analysis techniques based on computational fluid dynamics has reached the level of experiments. Therefore, this study was aimed at developing a numerical computational model for the oblique towing test of a UUV and estimating the hydrodynamic loads. Specifically, a 1:6 scale model of a manta-type UUV with a length of 12 m was developed. Simulations were performed using the commercial RANS-based viscous solver STARCCM (v. 17.06). The model was validated by comparing the numerical results with those of a towing tank experiment.
