This week Elvire Katramiz, PhD student in the EMO team, will present his work on :

"Research on mechanism of the freak wave generation based on High Order Spectrum(HOS)"

The freak wave is defined as the wave whose height is more than twice the significant wave height, which represents the extreme oceanic conditions. It has larger wave height and stronger nonlinearity, and can cause serious damage to the oceanic structures and ships. Research on the freak wave really needs to attract more and more attention, which is of vital importance to the design of the structures and ships to avoid disasters. So far, the mechanism of the freak wave generation is still not very clear. It remains to be further studied. As a nonlinear numerical model, High Order Spectrum (HOS), solving the  derivative terms by Fourier Transform method with  the properties of fast convergence and low computational cost, is considered to be a more suitable method to study freak waves.

The present includes the background, the HOS theory, the validation of the numerical model and some numerical simulation results.
