论文摘要
我们通过使用一种流体MHD MHD代码Magnus进行的数值模拟来测量非各向同性热传导对太阳能射流生成的影响。遵循Srivastava等人的工作。 （2018年），我们考虑了具有现实温度模型的大气状态，并通过在顶部色球层中运行的气压驱动器产生血浆的弹射。我们考虑通过改变磁场强度和驱动器的振幅来模仿通量管并进行参数研究的磁场。我们发现，在热传导的情况下，触发的喷气机表现出更大的能量和质量通量，它们的形状比对于理想的MHD方程而言更加准直，并且更渗透太阳电晕。低磁场使这些喷气机具有更大的能量，并且较大的磁场可降低由于加入导热性而导致的质量和能量的增强。
We measure the effects of non-isotropic thermal conduction on generation of solar chromospheric jets through numerical simulations carried out with the use of one fluid MHD code MAGNUS. Following the work of Srivastava et al. (2018), we consider the atmospheric state with a realistic temperature model and generate the ejection of plasma through a gas pressure driver operating in the top chromosphere. We consider the magnetic field mimicking a flux tube and perform parametric studies by varying the magnetic field strength and the amplitude of the driver. We find that in the case of thermal conduction the triggered jets exhibit a considerably larger energy and mass fluxes and their shapes are more collimated and penetrate more the solar corona than for the ideal MHD equations. Low magnetic fields allow these jets to be more energetic, and larger magnetic fields decrease the enhancement of mass and energy due to the inclusion of the thermal conductivity.
