The last decade has seen a significant increase in the number of studies devoted to wave turbulence. Many deal with water waves, as modeling of ocean waves has historically motivated the development of weak turbulence theory, which addresses the dynamics of a random ensemble of weakly nonlinear waves in interaction. Recent advances in experiments have shown that this theoretical picture is too idealized to capture experimental observations. While gravity dominates much of the oceanic spectrum, waves observed in the laboratory are in fact gravity–capillary waves, due to the restricted size of wave basins. This richer physics induces many interleaved physical effects far beyond the theoretical framework, notably in the vicinity of the gravity–capillary crossover. These include dissipation, finite–system size effects, and finite nonlinearity effects. Simultaneous space-and-time-resolved techniques, now available, open the way for a much more advanced analysis of these effects.

表面重力-毛细管波湍流实验

在过去十年中,专门研究波浪湍流的研究数量显着增加。许多涉及水波,因为海浪建模历来推动了弱湍流理论的发展,该理论解决了相互作用中弱非线性波的随机集合的动力学问题。实验的最新进展表明,这种理论图景过于理想化,无法捕捉实验观察结果。虽然重力在大部分海洋光谱中占主导地位,但由于波盆的大小有限,在实验室中观察到的波实际上是重力毛细波。这种更丰富的物理学引发了许多远远超出理论框架的交错物理效应,特别是在重力 - 毛细管交叉附近。这些包括耗散、有限系统尺寸效应和有限非线性效应。
