Study of Buoyant Hydromagnetic Flow in Rotating Fluids

地核内的流体流动问题，以及由此产生的发电能力，将从一个新的角度来研究，依赖于一个特定的模型，即在富含铁的内核继续固化的过程中，由外核底部释放的组成浮力流体驱动的地核内充分发展的流动。在这个模型中，有浮力的羽流从“烟囱”中喷出，穿过内核部分熔融的外层。这项研究将研究在旋转的、导电的流体中，由这些小尺度组成的浮力羽状物和斑点驱动的流动的本质，以及这种流动在地球磁场的产生中可能发挥的作用。

The problem of fluid flow within the Earth's core, and its resulting dynamo-generating capability, will be investigated from a new point of view, relying on a specific model of the fully developed flow in the core driven by compositionally buoyant fluid released at the base of the outer core as the iron-rich inner core continues to solidify. In this model compositionally buoyant plumes emanate from 'chimneys' piercing the partially molten outer layer of the inner core. The research will study the nature of flow driven by these small-scale compositionally buoyant plumes and blobs in a rotating, electrically conducting fluid, and the role this flow may have in the generation of the Earth's magnetic field.
