平滑粒子流体动力学(SPH)数值模拟中的重子物理
流体数值模拟 重子物理 恒星形成
2012/9/12
平滑流体动力学(SPH)数值模拟是我们研究星系形成与演化的一个重要工具。先介绍了SPH的基本原理和基本方程,然后以恒星形成、星系风反馈、AGN反馈和热传导为例,介绍了平滑流体动力学数值模拟中的重子物理及实施方法。这些模型在一定程度上都取得了成功,对更好地理解星系的形成和演化起到了促进作用。

Mass Transfer in Binary Stars using SPH. II. Eccentric Binaries
binaries close — stars evolution — hydrodynamics — methods numerical
2010/11/12
Despite numerous efforts to better understand binary star evolution, some aspects of it remain
poorly constrained. In particular, the evolution of eccentric binaries has remained elusive mainly becau...
The impact of numerical viscosity in SPH simulations of galaxy clusters
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/6
A SPH code employing a time-dependent artificial viscosity scheme is used to construct a large set of N-body/SPH cluster simulations for studying the impact of artificial viscosity on the thermodynami...

3D sph simulations of giant herbig-haro flows and jet-cloud interactions in star formation regions
smoothed particle hydro-dynamics star formation regions
2009/6/4
We review some recent results of three-dimensional smoothed particle hydro-dynamics (SPH) simulations of overdense, radiatively cooling jets in star formingregions. We discuss the structure and kinema...
