Rogue waves and analogies in optics and oceanography

We review the study of rogue waves and related instabilities in optical and oceanic environments, with particular focus on recent experimental developments. In optics, we emphasize results arising from the use of real-time measurement techniques, whilst in oceanography we consider insights obtained from analysis of real-world ocean wave data and controlled experiments in wave tanks. Although significant progress in understanding rogue waves has been made based on an analogy between wave dynamics in optics and hydrodynamics, these comparisons have predominantly focused on one-dimensional nonlinear propagation scenarios. As a result, there remains significant debate about the dominant physical mechanisms driving the generation of ocean rogue waves in the complex environment of the open sea. Here, we review stateof-the-art of rogue wave studies in optics and hydrodynamics, aiming to clearly identify similarities and differences between the results obtained in the two fields. In hydrodynamics, we take care to review results that support both nonlinear and linear interpretations of ocean rogue wave formation, and in optics, we also summarise results from an emerging area of research applying the measurement techniques developed for the study of rogue waves to dissipative soliton systems. We conclude with a discussion of important future research directions. the underlying carrier wave is considered sinusoidal at frequency ω whereas in hydrodynamics, the NLSE envelope modulates the Stokes wave which (to second-order) contains contributions at both ω and the second harmonic 2ω [31]. In addition, even though the terminology "optical wave breaking" is used in an NLSE context to describe the steepening of an optical envelope from nonlinear focussing [32], optical carrier waves themselves do not "break" or plunge as they do in hydrodynamics [33,34]. There are also important differences concerning measurements. Specifically, experiments in optical fibres generally measure only the time-domain envelope intensity, and information about carrier oscillations is not recorded. In contrast, measurements in hydrodynamics directly record the individual carrier wave amplitudes (although envelope information can be reconstructed straightforwardly [35]). Particular care must therefore be taken when comparing statistics between optics and hydrodynamics, because statistics in fibre optics experiments are determined

“…The fact that the present experimental study focuses on responses to irregular large amplitude waves, instead of steady-state responses in regular waves, increases further the complexity of an uncertainty analysis. For this reason the uncertainty analysis was not planned from the beginning in the experimental work conducted by Clauss et al (2009). A qualitative analysis can, however, be carried out.…”

“…This wave record has been analysed by different methods (Walker et al 2004;Slunyaev et al 2005;Veltcheva and Guedes Soares 2007;Cherneva and Guedes Soares 2008) aiming to explain the formation and evolution of the abnormal wave. A detailed temporal and spatial development of the NYW generated in the seakeeping basin can be found in Clauss and Klein (2011) and its modelling was done by Petrova et al (2011). Figure 7 describes an abnormal wave recorded during a 5day storm (November 16 to 21, 1997) Soares et al (2003) and was analysed with different methods in Slunyaev et al (2005), Veltcheva and Guedes Soares (2007).…”

This paper investigates the experimental and numerical vertical motion responses of a bulk carrier and a Roll-on/Roll-off ship in extreme seas. The experimental data were obtained from seakeeping tests with scaled models in head waves at two Froude numbers. The wave traces were predefined, corresponding to wave records measured during storms in the North Sea. These wave records are particularly interesting because each of them include one abnormal wave. The ship models, which are similar in length but different in their geometry, were tested in the same predefined wave conditions to investigate the influence of the hull geometry on the extreme vertical ship responses. Conclusions are derived by comparing directly the measured responses from the two models. Experimental data are also used as benchmark to validate the predictions by a partially nonlinear time domain seakeeping numerical model. The numerical model code is then used to generalize the comparative analysis between the two ships.

“…It has become a reference event for a large number of studies, representing a realistic extreme event for the analysis of the response of structures to such waves, e.g. see experiments in [10]. Note that other freak waves have been monitored and reported, see the review in [25] for instance.…”

On the equivalence of unidirectional rogue waves detected in periodic simulations and reproduced in numerical wave tanks

2016

View full text Add to dashboard Cite

This paper deals with the reproduction of unidirectional extreme events in a numerical wave basin. From a rogue wave measurement at a given location, experiments or numerical simulations are conducted with the same wave profiles using reproduction procedures. Although it is recognized that many different physical mechanisms may be at play in freak wave formation, reproduction procedures generally use frequency focusing to generate these high waves. This paper intends to assess the validity of this approach. In particular, it will focus on the relationship between an accurate reproduction of the free surface elevation and the accuracy of the corresponding wave kinematics inside the fluid domain. A highly nonlinear model is used to compute
