| 摘 要： | 基于光滑质点流体动力学(smoothed particle hydrodynamics,简称SPH)方法建立二维数值波浪水槽,利用推波板造波生成孤立波和不规则波,模拟结果跟实验值及解析解做了对比分析,结果令人满意.SPH数值水槽中生成的波浪具有明显的非线性,波浪能量沿程有所衰减,与物理水槽结果吻合良好.

| Abstract: | A two-dimensional numerical wave flume is developed based on Smoothed Particle Hydrodynamics method.Solitary and irregular waves are modeled.Comparisons of modeling results with analytical solutions and experimental results show sauisfactory agreement.The present numerical wave flume can also exhibit the decadent characteristics with wave propagations,agreeing well with results of the laboratory flume. |

| Keywords: | SPH numerical wave flume solitary wave irregular waves |
