摘要

波吸引子是一种在非平凡几何的分层/旋转流体中产生的内/惯性波自聚焦现象，由于能量在有限区域内积聚，导致湍流发展迅速。迄今为止，人们认为波吸引子的不稳定性应以三共振不稳定性的方式发展。在这项工作中，它表明，在一个特定的几何形状，接近真实的盆地几何形状，不稳定的行为可以充分不同于观察到的梯形设置。

Wave attractor in basin with underwater step: from discrete to continuous energy spectrum

Wave attractor, a phenomenon of internal/inertial wave self-focusing in a stratified/rotating fluid in non-trivial geometry, leads to the rapid turbulence development due to the energy accumulation on a limited area. It was believed until now that instability in a wave attractor should develop in the Triadic Resonance Instability way. In this work it is shown that in a specific geometry, close to real water basins geometries, the instability behaviour can sufficiently differ from that observed in a trapezoid setup.
