파랑-조류 상호작용에 의한 Freak Wave 발생기전 수치해석 기초연구

Abstract

In this paper, generation mechanisms of ocean freak waves are briefly introduced in the context of wave-current interaction phenomena. As an accurate and efficient numerical tool, the spectral method is presented with general features and specific treatment for the wave-current interaction problem. Accuracy and convergence of the developed spectral method is proved to be very promising. Due to the preliminary numerical results for a linear wave-maker problem, the numerical stability of the present method is reliable. It is therefore believed that the present numerical method seems to be very promising for the understanding and analysis of the freak wave generation mechanism due to wave-current interaction.
