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.

快速流动的等离子体与非磁化体的相互作用的数值模拟被用来隔离的电离层现象独特的这些条件-并比较电离层的响应与电离层的条件特性的等离子体流过磁化体。 这样，就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）模式模拟器具有球对称、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，其在本研究中的应用表明了计算流体动力学，航空航天工程，行星大气和高空大气学领域之间的互利协同作用。
