摘要
海浪是一种多向随机波。本文首先对常用的多向随机波的数值模拟方法——双迭加法进行改进,建议了频率方向对应法,并给出了合适的模拟参数。此法能产生比较符合实际的波浪。在此基础上论述了三维随机波的物理模拟方法,并对多向随机波试验中的几个重要问题进行了探讨。
Sea waves are random and three dimensional.For numerically simulating the multi-directional random waves,the double summation model which is frequently used has been improved and a single direction per frequeacy model is proposed in this paper.The resonable valties of the simulation parameters in this model are given and a more realistic wave field can be simulated.Based on the numerical simuation,the generation of direetional random waves in laboratory basin is investigated.Some important problems during experimeat with directiinal waves are inquired into.
