Nonlinear Potential Flow Models
C.J. Fitzgerald University of Oxford, Oxfordshire, United Kingdom
Abstract
Fully nonlinear potential flow (FNPF) models extend the regime of validity of linear potential flow models to include wave–body interactions in steep sea-states and/or involving large body displacements. More accurate predictions of wave kinematics, wave forces, and body motions can be obtained, compared to linear model predictions for interactions involving large free-surface and body displacements. First developed and widely applied in the fields of offshore engineering and naval hydrodynamics, such fully nonlinear models have only gradually been adopted in wave energy. The motivations of the development of fully nonlinear ...
