Application of a panel method to hydrodynamics of underwater vehicles

Boundary Element Method Applied to Added Mass Coefficient Calculation of the Skewed Marine Propellers

“…Sahin et al (1993) introduced the concept of added mass that generalized moving a desired object in different flow regimes [2]. Vernon et al (1988) considered a surface panel method for calculation of added mass matrices, [3], an approach which is relatively close to the present study. Added mass estimations for a multi-component deeply submerged vehicle were studied by Watt [4].…”

Influence of the wake model on the thrust of oscillating foil

“…The results show clearly that the potential approach is physically sound but the authors are well aware that there are some complex issues that may require a different approach including modelling of turbulence [28] and leading-edge vortices [3,4]. Besides, propulsion in water is dominated by the added mass effect [20,29,30] and it is worth mentioning that the Boundary Element Method is more suitable than other methods to estimate such an effect, as shown for example in [20,21,31,32]. The added mass effect is however beyond the scope of this study, the purpose of which was to propose an experimental validation for the numerical procedure in air, an approach that was proven fruitful [27,29,30].…”

RANS study of Strouhal number effects on the stability derivatives of an autonomous underwater vehicle

“…Hess and Smith [9] studied a moving body in an infinite fluid by a numerical potential flow simulation. Panel method is used by Sahin et al [10] and Mantia and Dabnichki [11] to estimate the stability derivatives of an underwater vehicle. In more recent years, numerical simulations based on RANS equations have been studied to determine stability derivatives.…”
