在这项工作中，我们在波浪水槽中进行了受控实验，以表示发生在激波带中的不同波-波相互作用。以孤立波为强迫条件，将不同的波幅和波事件之间的分离时间组合在一起。实验结果表明，湍流区的相互作用发展主要经历了三个阶段：喷流冲击、诱导飞溅和流动变成全三维湍流的区域。我们确定了相互作用发生的位置和相互作用的类型取决于两个主要因素，波幅之间的关系和这些波事件之间的分离时间。此外，我们还能够模拟在真实场景中观察到的波与波的相互作用。我们的目标是将这些发现与沼泽区的泥沙运输过程联系起来，在那里相互作用可能对泥沙运输机制和可能的形态变化产生潜在的影响。
In this work, we conduct controlled experiments in a wave flume to represent different wave-wave interactions occurring in the swash zone. Using solitary waves as the forcing condition, we combined different wave amplitudes with separation times between the wave events. Experimental results show that interactions developing in the swash zone present three main stages: A jet slamming, an induced splash, and a region where the flow becomes fully 3D turbulent. We identified that the location where the interactions occur and the type of interaction depends on two main factors, the relationship between the wave amplitudes and the separation time between these wave events. Additionally, we were able to mimic the wave-wave interactions observed in real-case scenarios. Our goal is to relate these findings to the sediment transport processes in the swash zone, where interactions could develop a potential impact on the sediment transport mechanism and possible morphological changes.
