The Numerical Simulation Research of Three Dimensional Irregular Wave Based on Wave Spectrum

Article Preview

Abstract:

Starting from observation statistics that oceanography has existed now and based on wave spectrum and the direction spectrum function, the three-dimensional irregular wave mathematical model is built with the method of halving frequency, and according to the wave spectral energy distribution, the number of frequency division and direction segmentation is studied. Last numerical simulation of three dimensional irregular wave is studied by using Matlab, the temporal and spatial wave simulation waveform is obtained. The simulation results show that this method can simulate three dimensional irregular wave accurately and fast.
