Paper No: OMAE2019-96505
... are fabricated in 1:20 model scale and installed in the shallow wave basin and exposed to the random waves. The outer to outer face distance between two wells changed by concerning the outer diameter (D) of the well such that 1D, 1.5D and 2D. The wave run-up, diffraction wave height and free surface water...

Paper No: OMAE2009-79645
... prediction methods in shallow water. One of the key issues identified was the diffraction/radiation calculation as this is the main foundation of all motion and mooring analyses. Comparisons of second order wave drift load transfer functions predicted by leading diffraction/radiation software for a typical...

Paper No: OMAE2008-57437
... with the predictions obtained using the numerical boundary-element model WAMIT. Body motions are also given for the floating model. The numerical modelling enables a comparison to be made between the diffraction pressure on a thin and thick walled cylinder of the same internal diameter. Oscillating Water Column...

Paper No: OMAE2004-51098
... also remains problematic in direct approaches The method proposed here allows to avoid these problems by solving a modified problem for the diffracted flow only, the incident wave field being explicitly described by potential flow models. A set of results, both on 2D and 3D geometries is presented...
