论文摘要
轴向几何形状可以接近许多涉及磁场的天体物理和地面场景。尽管平滑的颗粒流体动力学（SPH）技术已成功扩展到磁性流动力学（MHD），但基于这种技术的良好验证的轴对称MHD方案尚不存在。在这项工作中，我们在科学文献中填补了这一空白，并提出并检查了一种新型的轴对称MHD流体动力密码，可以应用于显示足够几何形状的物理问题。我们表明，按照这些轴对称假设构建的流体动力代码能够产生与具有等效分辨率但计算负载较小的标准3D-SPMHD代码相似的结果。
Many astrophysical and terrestrial scenarios involving magnetic fields can be approached in axial geometry. Although the smoothed particle hydrodynamics (SPH) technique has been successfully extended to magneto-hydrodynamics (MHD), a well-verified, axisymmetric MHD scheme based on such technique does not exist yet. In this work we fill that gap in the scientific literature and propose and check a novel axisymmetric MHD hydrodynamic code, that can be applied to physical problems which display the adequate geometry. We show that the hydrodynamic code built following these axisymmetric hypothesis is able to produce similar results than standard 3D-SPMHD codes with equivalent resolution but with much lesser computational load.
