Abstract:
An investigation of lift forces acting on gravity base foundations is presented, utilizing the Computational Fluid Dynamics (CFD)-based Virtual Free Surface (VFS) reduced modeling technique. The paper raises awareness of the significant vertical loads that may ensue when currents and waves are subjected to a bluff body. An efficient solution to this design challenge is proposed and analyzed by introducing an under-body diffuser. The structure is tested and analyzed for various pure wave, pure cu...     »
