三维波峰的数值模拟

Numerical simulation of three dimensional wave crest

给出了三维波峰的定义,描述了波峰临界值的确定过程,分析了三维随机海浪的方向谱和三维随机海浪的数学描述,在MATLAB环境下设计了随机海面波峰的数值模拟程序,并给出了深水波峰的三维空间模型及其在不同方向传播参数和不同方向函数下平面分布的变化。

This paper presents a definition of wave crest and describes the procedure to detect the boundary line of wave crest area. On the basis of random wave theory and directional wave spectrum, A MATLAB program is designed to simulate random wave crests for various directional spectral conditions in deep water. Distributions of wave crests with different directional spreading parameters and different directional functions are obtained.
