Abstract
In the present work is presented a recently developed fully-nonlinear spectral Numerical Wave Tank (NWT) model, named HOST-wm2, and its capabilities for reproducing highly-nonlinear evolutions in a wavetank are evidenced on experimental comparisons. This fully-spectral model is based on a Higher-Order Spectral (HOS) method, which ensures high levels of accuracy and efficiency, thanks to the fast resolution made by FFTs only. This numerical method is dedicated to model wave basins and a specific care is paid to fit the experimental wavetank characteristics (are included, the physical geometry of the wavetank, the snake-type wavemaker, an absorbing beach, ...). The numerical simulations are successfully compared to experiments conducted in cooperation with Ocean Power Delivery (OPD) in the wavetank of the Ecole Centrale de Nantes (ECN). Comparisons for wave elevation and pressure fields under highly-nonlinear steep 2D waves are reported. The usefulness of the presented NWT to assist experiments is also illustrated on the assessment of the procedure used to extract the pressure gradient from the experimental pressure signals.
