Numerical Study of Focused Wave Impact on a 2-D Floating Body Using CIP-based Method
In rough seas, marine structures such as ship, platform, etc.frequently experience highly nonlinear phenomena such as slamming, water on deck, wave impact by green water and capsizing due to large-amplitude waves.Investigation of such wave-body interaction problem is of considerable importance in engineering application.This paper uses a constrained interpolation profile (CIP)-based Cartesian grid method to numerically investigate the focused wave impact on a two-dimensional floating body, which is validated against to a newly performed experiment.In the experiment, focused wave is generated and a box-shaped floating body with a superstructure is utilized.Validation computations on the experiment are performed by the CIP-based Cartesian grid method, in which the THINC scheme (THINC, tangent of hyperbola for interface capturing), is used for interface capturing.The highly nonlinear wave-body interactions, including large amplitude body motions and water on deck are numerically investigated and compared with experimental data.Good agreements are achieved to show the ability of the presented model for extremely nonlinear wave-body interactions.
