Abstract

Abstract

Extreme breaking waves are one of the key factors causing the damage of ocean engineering structures.So it is very meaningful to develop the theory for generating the extreme waves and to investigate the extreme wave characteristics.The method for generating three dimensional focusing waves is proposed using the principal that waves propagate faster for longer waves and slower for shorter waves.Wave packet transformation is simulated by linear calculation and a numerical model based on the Boussinesq equations and the finite element method to verify the proposed method.The calculated results show that the proposed method can generate expected focusing waves. The effects of the associated wave parameters such as the center frequency,frequency width and the type of frequency spectrum on the focusing waves are also discussed.
