Development of a Liquid Sodium Laboratory Model of the Earth's Outer Core

9903958本仪器开发项目旨在通过仔细控制液态钠中的实验，了解液态金属流动(发电机作用)产生的磁场。目标是更好地描述和更好地理解发电机理论，该理论试图解释地球和其他天体的磁场产生。莱斯罗普等人。将开发一项新的实验，它将由旋转的内外球面边界组成，中间有对流的液态钠。此外，他们还将对这项实验与加州大学圣克鲁斯分校的加里·格拉茨迈尔进行的数值模拟进行直接比较。这些比较将对现代地球外核模拟中使用的模型假设进行直接测试。

9903958LathropThis instrumentation development project seeks to understand magnetic field generation by the flow of liquid metals (dynamo action) through carefully controlled experiments in liquid sodium. The goal is to better characterize and to better understand the dynamo theory that seeks to explain magnetic field generation for the Earth and other astrophysical bodies. Lathrop et al. will develop a new experiment which will consists of a rotating inner and outer spherical boundary with convecting liquid sodium in between. Additionally, they will undertake a direct comparison between this experiment and numerical simulations to be performed by Gary Glatzmaier at the University of California, Santa Cruz. These comparisons will afford a direct test of the model assumptions used in modern simulations of the earth's outer core.***
