Web1 Aug 2024 · This study's main objective is to investigate the scale effect on the benchmark DARPA Suboff submarine hull form's resistance and self-propulsion characteristics. The study's secondary objective is to explore the feasibility of the 1978 ITTC performance prediction method for submarines' power prediction. Web1 Mar 2024 · Ashok and Smits (2013) carried out a flow visualization experiment using a wind tunnel to understand how the drift angle affects the mean flow and turbulence of the SUBOFF submarine. Krishnankutty (2013) experimentally investigated the effect of variation of the vehicle length on the hydrodynamic forces of axisymmetric underwater vehicles. WebMotion Mechanism (PMM) experiment performed on the SUBOFF submarine model. The dynamic mesh method is adopted to simulate the maneuvering motions of pure heaving, pure swaying, pure pitching and pure yawing. The hydrodynamic forces and moments acting on the maneuvering submarine are obtained. Consequently, by analyzing these results, the … how high up is denver
