Velocity autocorrelation function in anisotropic MHD turbulence

This is ASCII data for Figure 2 from Pratt, Busse, Mueller 2020<br>"Lagrangian Statistics for Dispersion in Magnetohydrodynamic<br>Turbulence". The time values are provided with Figure 1.<br><br>The figure shows the evolution of the velocity autocorrelation function<br>for three simulations (HNOVIS: incompressible isotropic hydrodynamic<br>turbulence, ANOVIS0: isotropic magnetohydrodynamic turbulence, and<br>ANOVIS3: anisotropic magnetohydrodynamic turbulence). The velocity<br>autocorrelation function for the anisotropic MHD simulation ANOVIS3 is<br>separated into velocities in the direction parallel and perpendicular to<br>the mean magnetic field. Each curve is produced from the average of<br>at least 4 independent initial times.<br>

本数据集为Pratt、Busse与Mueller于2020年发表的论文《磁流体动力学湍流中的弥散拉格朗日统计》（Lagrangian Statistics for Dispersion in Magnetohydrodynamic Turbulence）中图2对应的ASCII数据。时间参数与图1一并给出。

该图展示了三组模拟实验的速度自相关函数演化过程：HNOVIS（不可压缩各向同性流体动力学湍流，incompressible isotropic hydrodynamic turbulence）、ANOVIS0（各向同性磁流体动力学湍流，isotropic magnetohydrodynamic turbulence）以及ANOVIS3（各向异性磁流体动力学湍流，anisotropic magnetohydrodynamic turbulence）。

针对各向异性磁流体动力学（Magnetohydrodynamic，MHD）模拟ANOVIS3，其速度自相关函数会拆分为与平均磁场平行及垂直方向的速度分量对应的函数。

每条曲线均由至少4组独立初始时刻的数据集平均计算得到。
