Time domain computation of nonlinear diffraction loads upon three dimensional floating bodies
- SIREHNA, Nantes (France)
The diffraction of nonlinear regular waves of permanent form by three dimensional bodies is simulated numerically. The computation is based on a boundary integral equation method, with a mixed Euler-Lagrange approach for the time-stepping. The method is an extension of a previously developed linear time domain computational model for free surface flows (Ferrant 1993b). The behavior of the nonlinear model has first been tested on radiation and diffraction problems for submerged bodies, with satisfactory results (Ferrant 1994). In the present paper, the author reports on the extension of this model to the diffraction of nonlinear waves upon surface piercing bodies. Some numerical results obtained in the case of a bottom-mounted vertical cylinder in water of finite depth are presented and discussed.
