Abstract

We investigate the complex dynamics of narrow-band wave fields described by the viscous Benjamin–Ono equation, a model of significant relevance in hydrodynamics. Through detailed numerical simulations, we analyze the role of Reynolds viscosity in shaping statistical moments, energy spectra, and the occurrence of extreme internal wave events. In particular, we show that freak waves of moderate amplitude can occur in viscous fluids.

粘性Benjamin-Ono方程模型中弱分层流体内波的不规则动力学

我们研究了由粘性Benjamin-Ono方程描述的窄带波场的复杂动力学，这是一个与流体动力学有重要关系的模型。通过详细的数值模拟，我们分析了雷诺数黏度在统计矩、能谱和极端内波事件发生中的作用。特别是，我们证明了中等振幅的畸形波可以出现在粘性流体中。
