Assessment of the capability of the Nonlinear Schrodinger equation and the High-order spectral method to simulate propagation of random waves

摘要

Numerical simulations performed by nonlinear Schrödinger equation and high-order spectral method are compared with the laboratory experiments in this paper. A detailed assessment of the capability of the two wave models to descript irregular waves propagation is carried out. It is found that the HOS method shows a better agreement with the experiments in terms of simulating the wave parameters, while HOS method shows a little overestimation in predicting extreme waves.
