论文摘要
我们提出了一种新的1D多物理模拟代码，其用例使用旨在但不限于行星气氛和行星增生模型的流体动力学逃逸问题。我们的配方治疗了任意数量的物种，通过摩擦定律将它们融合在一起，允许它们进行多频通量限制的辐射传输，并在高能辐射带中进行轨迹延伸前线。除了将各种已知的数值溶液技术耦合在一起，通过使用均衡的方案，我们对深静水压气大气的数值稳定性进行了处理，从而防止了大气中或流出的无物质驱动。我们演示了单个代码模块的正确身体行为，并介绍了很少的简单新应用，例如结合核心驱动的质量损失和UV-drivenatmospheric逃生的概念验证模拟，以及完全依赖时间的核心偏移巨型巨型巨型行星。 Thecode的多物质性质开辟了探索模拟的区域，这些模拟对主要的大气物种不可知，并可以导致先进的行星进化方案的实现。
We present a new 1-D multi-physics simulation code with use cases intended for, but not limited to, hydrodynamic escapeproblems of planetary atmospheres and planetary accretion models. Our formulation treats an arbitrary number of species asseparated hydrodynamic fields, couples them via friction laws, allows for a multi-band flux-limited radiation transport, and tracksionization fronts in high-energy irradiation bands. Besides coupling various known numerical solution techniques together, weimprove on the numerical stability of deep hydrostatic atmospheres by using a well-balanced scheme, hence preventing unphysicaldriving of atmospheric in- or outflow. We demonstrate the correct physical behaviour of the individual code modules and presenta few simple, new applications, such as a proof-of-concept simulations of combined core-powered mass-loss and UV-drivenatmospheric escape, along with a fully time-dependent core-collapse giant planet simulation. The multi-species nature of thecode opens up the area of exploring simulations that are agnostic towards the dominant atmospheric species and can lead toimplementations of advanced planetary evolution schemes.
