Abstract

Freak wave is a kind of instantaneous disastrous wave with large wave height, which has great destructive effect on the navigation of ships at sea. Based on the Boussinesq equation, a phase-focusing model for focusing simulation of freak wave is established, and the numerical generation of freak wave is realized. Through the calculation results, the evolution process and the non-linear characteristic parameters of freak wave are analyzed and discussed. The following conclusions are drawn: phase-focusing model based on Boussinesq equation can generate freak wave when the phase angle distribution is smaller than 1.6π. The change of phase angle distribution has less influence on skewness and more influence on kurtosis.
