The strong-field regime of the geodynamo

这个博士项目的主要目的是更好地了解行星核心的发电机过程，并研究行星旋转速率和对流驱动等关键参数的影响。特别是，我们将研究强场制度，通过使用一个强加的磁场。在实现这一点之后，我们可以移除施加的磁场，看看发电机过程是否能够在没有它的情况下运行，从而创建一个像许多行星一样产生磁场的模型。总而言之，我们对这个项目的目标是：1。确定磁场产生足够强的磁力以影响磁对流动力学的条件。2.在自激发电机过程中通过磁对流产生相同的区域后，产生强场区域。将这些结果外推到行星核心条件

The main aim for this PhD project is to develop a better understanding of the dynamo process in planetary cores, and study the influence of key parameters such as the planet rotation rate and the convective driving. In particular we will study the strong-field regime through the use of an imposed magnetic field. After achieving this, we can remove the imposed field and see whether the dynamo process is able to operate without it, thus creating a model which produces a magnetic field in the same way as many planets. To summarize, our goals for this project are:1. Determine the conditions in which a magnetic field yields strong enough magnetic forces to affect the dynamics of a magnetoconvective flow.2. Produce a strong-field regime in a self-excited dynamo process after producing the same regime through magnetoconvection.3. Extrapolate these results to planetary core conditions
