“…Hence, there is a need to understand these free surface effects. This paper extends upon the work by Ling et al (2022d), investigating the influence of submarine geometry on the interaction behaviour between the submarine and the free surface. The geometry of an underwater vehicle is the result of complex design processes and trade-offs which aim to balance the operational, financial, and technological requirements.…”

“…Ling et al [7] conducted a numerical study to examine the hydrodynamics of the DARPA suboff under free surface effect. Ling et al [8] used CFD to investigate the effect of length-to-diameter ratio on the performance of a submarine operating near the free surface. Dogrul [9] studied the hydrodynamics of a submarine moving close to a free surface.…”

This paper investigates the hydrodynamic performance of a model scale submarine operating near the free surface using Computational Fluid Dynamics. The RANS approach has been adopted to model the flow around the submerged body. The resistance predictions of the submarine model validated against available experimental data, and then the variation of the acting forces on the submarine was investigated in a constant submergence depth. The results were presented in terms of drag coefficient, flow field visualizations and the free surface deformations, for the better understanding of the hydrodynamics of the submarine at near surface operation.
