Fast robust design optimisation methods applied to ship hydrodynamics

摘要

In this work the benefits of Open Source design optimisation methods applied tornship hydrodynamics were highlighted, in particular the advantages of using the CFD platform OPENFOAM coupled with the multi-objective design optimisation software DAKOTA. Different approaches of geometrical shape parameterisation were evaluated for a couple of test cases, including minimisation of ship forward resistance while maximising displacement, as well as design optimisation of rudder and other appendages for different speed, angle of attack and other operating conditions.
