Improving the Inertial Wave Turbulence approximation

从行星核心、气态行星到吸积盘，旋转流体在自然界中无处不在。每一个这样的系统都支持一种丰富的波族——称为惯性波——如果旋转气流受到干扰，惯性波就会被激发。这种最初的兴奋现在在各种情况下都得到了很好的理解，但当波浪在成长过程中开始与自身相互作用时会发生什么，我们就不得而知了。最近发现了几种新的不稳定性，它们描述了引力波如何相互作用。这个博士项目将探索如何使用这些来更新弱波湍流近似。

Rotating fluids are ubiquitous in nature ranging from planetary cores and gaseous planets to accretion disks. Each such system supports a rich family of waves - called inertial waves - which become excited if the rotating flow is disturbed. This initial excitement is now relatively well understood in a variety of situations but what happens when the waves start to interact with themselves as they grow is not. Recently a few new types of instability have come to light which describe how the waves can interact. This PhD project will explore how these can be used to update a weak wave turbulence approximation.
