Comparative Studies of the Interaction and Ionospheric Processes at a Variety of Different "Non-Magnetic" Solar System Bodies

通过对快速流动等离子体与非磁化体相互作用的数值模拟，分离出这些条件下特有的电离层现象，并将电离层响应与等离子体流过磁化体时特有的电离层条件进行比较。通过这种方式，我们可以更好地了解两种电离层的电离层形态及其太阳风或磁层驱动因素。磁流体动力学（MHD）模型模拟器具有球对称、多物种能力，在电离层区域达到10 km的空间分辨率。数值代码是为空间天气研究目的而开发的，它在这项研究中的应用表明了计算流体动力学、航空航天工程、行星大气和航空学领域之间的互利协同作用。

Numerical simulations of the interactions of fast flowing plasma with non-magnetized bodies are used to isolate the ionospheric phenomena unique to those conditions - and to compare that ionospheric response with ionospheric conditions characteristic of plasma flow past magnetized bodies. In this way, ionospheric morphology and its solar wind or magnetospheric drivers are better understood for both types of ionospheres. The Magneto-Hydrodynamic (MHD) model simulator features spherically symmetric, multi-species capability, and achieves 10 km spatial resolution in the ionospheric regions. The numerical code is developed for Space Weather research purposes, and its application in this research demonstrates the mutually beneficial synergy between the fields of computational fluid dynamics, aerospace engineering, planetary atmospheres, and aeronomy.
