slamming forces on a ship s bow due to steep or breaking waves,broaching-to problems in steep waves and motions of a plann.

线性波浪理论已成功地应用于许多船舶耐波性研究 ,但还有许多耐波性问题有待于对波浪运动学作深入研究 ,例如由于陡波或碎波对船首的砰击力 ,陡波中的横甩及波浪中滑行艇的运动等。

Experimental study on fine sediment concentration under breaking waves;

破碎波作用下粉沙悬移质浓度垂向分布的实验研究

This paper presents the experimental study on the multi-directional focusing waves and breaking waves,which are generated in wave basin by using focusing wave method with two different spectrums(constant wave amplitude spectrum and constant wave steepness spectrum) and two different water depths.

该文采用两种不同频谱形式(等波陡和等波幅)、不同水深,通过波浪聚焦的方法在水池中产生多向聚焦波和破碎波,实验研究了破碎波的波面特性、破碎波的破碎指标及传播过程中的频谱变化,结果表明频谱形式、水深及方向分布对破碎波浪特性有明显的影响;波浪传播过程中频谱高频部分有明显的变化;波浪破碎过程中的能量损失主要来自波浪频谱高频部分。
