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.

地球核心内的流体流动问题， 由此产生的发电能力，将调查从 一个新的角度来看，依靠一个具体的模式，充分 由组分浮力流体驱动的岩心中的发展流动 作为富含铁的内核释放在外核的底部 继续固化。 在这个模型中， 羽状物从“烟囱”中发出， 内核层。 该研究将研究 由这些小规模的成分浮力羽流驱动的流动， 旋转的导电流体中的斑点，以及 这种流动可能对地球磁场的产生有影响。
