| 摘 要： | 基于粘性数值波浪水池技术,对短峰不规则波进行数值模拟.文中首先改进了长峰不规则波的数值模拟方法,并使用改进后的方法进行了不同海况下长峰不规则波数值模拟,模拟效果明显改善,数值模拟结果与目标值储吻合相当好.之后进行了短峰不规则波的数值模拟,模拟结果与特征值/目标谱也相当接近.

| Abstract: | The short-crested irregular waves are reproduced by using a viscous numerical wave tank simulation technique.First,the simulation method for long-crested irregular waves is improved in this paper.The improved method is used for the simulating of long-crested irregular waves for different sea states.Finally,the results of numerical simulation are compared with the targets and show quite good agreement with them.Numerical simulation of short-crested irregular waves are carried out.The results also show good a... |
