相对论多流体等离子体中的弛豫态

Relaxed States in Relativistic Multi-Fluid Plasmas

Jesse Pino, Hui Li, Swadesh Mahajan

摘要:

导出了具有相对论体积运动和热运动的多组分带电流体等离子体的演化方程。它示出,一个最小的流体耦合模型允许一个自然铸造的广义涡的流体运动和电磁场同等对待的演化方程。平衡可以使用基于在能量和螺旋度约束下最小化总涡度拟能的变分原理来找到。这些平衡的一个子集对应于最小能量。这些状态的方程与示例的解决方案显示的结构的放松状态。

英文摘要:

The evolution equations for a plasma comprising multiple species of charged fluids with relativistic bulk and thermal motion are derived. It is shown that a minimal fluid coupling model allows a natural casting of the evolution equations in terms of generalized vorticity which treats the fluid motion and electromagnetic fields equally. Equilibria can be found using a variational principle based on minimizing the total enstrophy subject to energy and helicity constraints. A subset of these equilibria correspond to minimum energy. The equations for these states are presented with example solutions showing the structure of the relaxed states.
