论文摘要
轴向几何形状可以接近许多涉及磁场的有趣的陆生和天体物理场景。即使Lagrangian平滑颗粒流体动力学(SPH)技术已成功扩展以处理磁性流动力(MHD)问题,但不存在基于SPH技术的良好验证的轴对称MHD方案。在这项工作中,我们提出并检查了一个新的轴对称MHD流体动力代码,该代码可用于显示足够几何形状的天体物理和工程问题。我们表明,基于这些轴对称前提的流体动力代码能够与标准的3D-SPHMHD代码产生相似的结果,但计算工作减少得多。
Many interesting terrestrial and astrophysical scenarios involving magnetic fields can be approached in axial geometry. Even though the Lagrangian smoothed particle hydrodynamics (SPH) technique has been successfully extended to handle magneto-hydrodynamic (MHD) problems, a well-verified, axisymmetric MHD scheme based on the SPH technique does not exist. In this work, we propose and check a new axisymmetric MHD hydrodynamic code that can be applied to astrophysical and engineering problems which display an adequate geometry. We show that a hydrodynamic code built on these axisymmetric premises is able to produce similar results to standard 3D-SPHMHD codes but with much lesser computational effort.
