中文摘要:波浪数值水槽是波浪研究方面的一个十分重要的实验装置。目前针对造波水槽所展开的数值或实验研究,多将造波系统的设定参数作为波浪的参数,而未考虑设定参数与实际参数之间的误差。利用推板造波的实验装置进行造波,并借助视频拍摄来捕捉造波板的运动,而波浪参数则由波高仪的数据采集来得到。推板造波的过程,则用光滑粒子方法来进行数值模拟。造波过程中,造波板的运动同样采用实测的参数,并计算了不同时刻的波形曲线和水面高度随时间的变化。光滑粒子的模拟结果与实验结果比,吻合的非常好。
外文摘要:Numerical wave tank is an important device for wave researches. At presents,the wave parameters are always defined as the setting value of the wave-making system in many numerical and experimental studies. The difference between the setting values and the actual values are not taken into account. The wave making are carried out by the piston wave maker device,during the experiment,the motion of piston plane is captured by the filming.And wave gauges is used here to collect datas. In the piston wave-making process,a numerical simulation is carried out here by the smoothed particle hydrodynamics. The parameters of the motion of the piston wave maker are measured by ourselves. And the wave form at different time instants are calculated,as well as the time evolution of free surface level. The results of smoothed particle methods agree well with the experimental results.
