... surface, as described in Kharif et al. (2009), Osborne (2010). The MI can be also modeled within the context of the nonlinear Schrödinger equation (NLS), a wave envelope evolution equation that describes the motion of weakly nonlinear water wave packets in time and space Zakharov (1968). In fact, the NLS...

... in intermediate and deep water regions. Further, for each wave packet, two different amplitudes are considered, corresponding to non breaking and breaking cases. The time evolution of the selected harmonics are analyzed using the Inverse Fast Fourier Transform (IFFT), to show the propagation of the spurious, free...

... INTRODUCTION For improved seakeeping tests and wave loading predictions, steep tailored design waves like focused events are requested in laboratory wave basins. The wavemaker motion that will correctly reproduce such large deterministic wave packets is needed both in two and three dimensions...

... ABSTRACT A potential flow model for linearized ship seakeeping in time domain is presented. The numerical algorithm is briefly sketched. The transient test technique, based on the interaction of a mathematical wave packet with the advancing ship, is numerically simulated and allow to recover...

The Kortweg-deVries (KdV) type equation can be used to explain the evolution of internal wave packets and linked to satellite image observations.

As a consequence, it must be stated that high irregular wave tests are not sufficient for evaluating design wave loads. Only tests...

... Abstract: The interaction between two colliding monochromatic wave packets in water of finite depth is investigated through numerical experiments. A two dimensional numerical wave tank is used for this purpose. Each end of this flume is a piston acting as a wavemaker, and can be switched...
