Abstract
By order of the Defence Materiel Organisation (DMO) of the Royal Netherlands Navy (RNLN) the Maritime Research Institute Netherlands (MARIN) conducts studies regarding the hydrodynamics and manoeuvring capabilities of submarines. Together, they are actively involved in the Submarine Hydrodynamics Working Group (SHWG). The SHWG is a group of international navies from Australia, Canada, Germany, France, UK, USA and The Netherlands. In general, the navies team up with local research institutes. Informal meetings are held every eighteen months to discuss non-classified subjects related to hydrodynamics of submarines. Within the SHWG, a study was initiated to assess the state-of-the-art in computations of viscous flows around a submarine and to accelerate and improve research and development of numerical submarine hydrodynamics. In the study, a common testcase was defined for which each navy was asked to generate predictions based on their best approach in viscous-flow calculations. The central question in the study is to demonstrate the capability of viscous-flow solvers to reproduce the flow field around and the forces acting on a submarine hull form. This article presents the work conducted by the Dutch team.
