Improving the Inertial Wave Turbulence approximation

旋转流体在自然界中无处不在，从行星核和气态行星到吸积盘。每一个这样的系统都支持一个丰富的波族--称为惯性波--如果旋转流受到扰动，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比较好的理解，但当波开始与它们自己相互作用时，当它们成长时，会发生什么却不是。最近，几种新的不稳定性类型被发现，它们描述了波如何相互作用。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.
