行星形成数值模拟的研究现状与未来需求Ⅰ:原行星盘中的气体与尘埃动力学
发布时间:2018-11-13 10:51
【摘要】:行星在气态的原行星盘中形成,而行星形成的全过程几乎都与原行星盘中气体与尘埃的动力学密不可分。原行星盘中气体与尘埃的动力学过程涉及包括非理想磁流体、化学、热辐射、非热辐射、空气阻力等诸多效应的作用以及它们之间的相互耦合,因而关于行星形成问题的研究往往需要进行数值模拟,并对计算工具有着很高的要求。对研究行星形成问题所涉及的物理过程进行概述,简要介绍这些研究中主要使用的数值方法/算法,以及国际上与之相关的最新进展。最后,对未来行星形成领域的发展及其对数值工具的需求作以展望。
[Abstract]:Planets are formed in gaseous protoplanetary disks, and the whole process of planetary formation is almost inextricably related to the dynamics of gas and dust in the original planetary disks. The kinetic processes of gas and dust in the original planetary disk are related to the effects of non-ideal magnetic fluid, chemistry, thermal radiation, non-thermal radiation, air resistance, and their mutual coupling. Therefore, the study of planetary formation problem often needs numerical simulation, and has high requirements for computing tools. This paper summarizes the physical processes involved in the study of planetary formation, briefly introduces the numerical methods / algorithms mainly used in these studies, and the latest developments related to them in the world. Finally, the future development of planetary formation and its demand for numerical tools are prospected.
