中文摘要
我们发展了求解相对论阻性辐射磁流体动力学方程的数值格式。使用半隐式格式可以在不妨碍大规模并行计算的情况下降低计算成本。然后,我们用我们的程序研究了辐射对相对论磁重联的影响。我们发现,辐射阻力减慢了流出速度,导致能量转换率降低。
英文摘要
We develop numerical schemes for solving relativistic resistive radiation magnetohydrodynamic equations. Using semi-implicit scheme, we can lower computational costs without preventing massive parallel computing. Then we adopt our code to study radiation effects on the relativistic magnetic reconnection. We found that a radiation drag force slows down an outflow speed, leading to a reduction of energy conversion rate.
