Rogue Waves within the Framework of Weakly Nonlinear Evolution Equations – Applicability and Limitations
Wednesday, November 16, 2016, 3:00pm to 4:00pm | Room 5-314
Extreme ocean waves, also referred to as freak or rogue waves (RWs), are known to appear without warning and have a disastrous impact on ships and offshore structures as a consequence of the substantially large wave heights they can reach. Studies on RWs have recently attracted scientific interest due to the interdisciplinary universal nature of the modulation instability (MI) of weakly nonlinear waves as well as for the sake of accurate modeling and prediction of these mysterious extremes. Indeed, exact solutions of the nonlinear Schrödinger equation provide advanced backbone models that can be used to describe the dynamics of RWs in time and space, providing therefore deterministic prototypes that can be investigated to reveal novel insights of MI. A wide range of recently conducted experiments and numerical simulations on breathers as well as prediction aspects will be discussed. Furthermore, the existence of such localized structures in realistic sea state conditions will be presented as well.
