CSEDI Collaborative Research: Next Generation Modeling of Core Turbulence via Combined Laboratory, Numerical and Theoretical Models

地磁场是由所谓的“流体发电机”产生的。这台发电机是由地球熔融金属核心中快速旋转的湍流对流驱动的。然而，快速旋转的核型对流湍流还没有得到准确的模拟。该项目的目标是提供第一个对快速旋转、湍流、核心型对流的跨学科量化。通过这样做，我们将大大加强我们对将地球变成巨型磁体的核心流动的理解。我们将开发新一代地核湍流对流模型，以解决当前发电机发电模型中的重大局限性。这些模型将结合领先的实验室旋转对流实验与最先进的有限元模型，以及先进的、渐近简化的旋转对流系统理论模型。我们将产生的数据对于地核和其他行星发电机的模型者，以及太阳和恒星对流带和发电机的模型者，以及地球气候和行星大气的模型者，将是至关重要的。渐近简化的建模工具将通过地球科学计算基础设施(CIG)网站公开提供。此外，我们将通过正在进行的实习，为对结合科学和纪录片制作感兴趣的学生开发一个独特的地球科学教育电影资料库。

The geomagnetic field is generated by a so-called `fluid dynamo'. This dynamo is driven by rapidly rotating, turbulent convection in Earth's molten metal core. Yet rapidly rotating core-style convective turbulence has not been accurately simulated. The goal of this project is to provide the first cross-disciplinary quantification of rapidly rotating, turbulent, core-style convection. In doing so, we will greatly strengthen our understanding of the core flows that turn Earth into a giant magnet.We will develop next-generation models of turbulent convection in Earth's core to address significant limitations in current models of dynamo generation. These models will combine leading laboratory rotating convection experiments with state-of-the-art finite element models and with advanced, asymptotically reduced theoretical models of rotating convection systems. The data we will produce will be of fundamental importance to modelers of Earth's core and other planetary dynamos, as well as modelers of solar and stellar convection zones and dynamos, and modelers of Earth's climate and planetary atmospheres. The asymptotically reduced modeling tools will be made openly available through the Computational Infrastructure for Geosciences (CIG) website. Furthermore, we will develop a unique library of geoscience educational films, via an ongoing internship for students interested in combining science and documentary filmmaking.
