本文对浅水中孤立波的破波过程进行了直接数值模拟,以量化有效破波期间的能量耗散。我们发现这种耗散可以用基于泰勒假设的惯性模型作为局部波高、深度和海滩坡度的函数来预测。得到了破碎波在浅坡上的耗散率与局部破碎参数的关系。接下来,我们使用经验关系将局部波浪参数与离岸条件联系起来。这使得能量耗散可以根据初始条件进行预测。相对于理论标度,我们得到了数值数据的很好折叠。
We present direct numerical simulations of breaking solitary waves in shallow water to quantify the energy dissipation during the active breaking time. We find that this dissipation can be predicted by an inertial model based on Taylor’s hypothesis as a function of the local wave height, depth and the beach slope. We obtain a relationship that gives the dissipation rate of a breaking wave on a shallow slope as a function of local breaking parameters. Next, we use empirical relations to relate the local wave parameters to the offshore conditions. This enables the energy dissipation to be predicted in terms of the initial conditions. We obtain good collapse of the numerical data with respect to the theoretical scaling.
