论文摘要
该论文提出了一种使用血浆矩和磁场数据得出太阳风的湍流加热的新方法。我们开发该方法，然后将其应用以计算1AU处太阳风质子等离子体的湍流加热。该方法采用了扩展的太阳风等离子体的两种物理特性，波颗粒热力学平衡和熵速率的传输。我们分析了从风s/c获取的血浆矩和现场数据集，以计算（i）波动的磁能，（ii）相应的相关长度，以及（iii）湍流加热速率。我们确定了它们与太阳风速的关系，以及这些关系相对于太阳风和星际冠状质量射血等等离子体的变化。
The paper presents a new method for deriving turbulent heating of the solar wind using plasma moments and magnetic field data. We develop the method and then apply it to compute the turbulent heating of the solar wind proton plasma at 1AU. The method employs two physical properties of the expanding solar wind plasma, the wave-particle thermodynamic equilibrium, and the transport of entropic rate. We analyze plasma moments and field datasets taken from Wind S/C, in order to compute (i) the fluctuating magnetic energy, (ii) the corresponding correlation length, and (iii) the turbulent heating rate. We identify their relationships with the solar wind speed, as well as the variation of these relationships relative to solar wind and interplanetary coronal mass ejection plasma.
