Zhang, HD., Guedes Soares, C., Chalikov, D. and Toffoli, A. (2016), “Modelling the Spatial Evolutions of Nonlinear Unidirectional Surface Gravity Waves with Fully Nonlinear Numerical Method”, Ocean Engineering, Vol. 125, pp. 60-69

Statistical properties of the mechanically generated unidirectional nonlinear wave series are simulated directly with the fully nonlinear Chalikov-Sheinin model, which is based on a non-stationary conformal surface-following coordinate transformation that reduces the principal equations of potential waves into two simple evolutionary equations for the elevation and the velocity potential on the surface. Meanwhile, the numerical simulations performed by the temporal version of modified nonlinear Schrödinger equation (MNLS) are also compared with the laboratory experiments in this study. As expected, except for the wave height distribution, Chalikov-Sheinin or simply called ChSh model is more consistent with the observed statistics, particularly in the aspects of fourth-order normalized cumulants and wave crest distribution in the presence of strong nonlinearity.
