1/nu区的相对论新经典径向通量

Relativistic neoclassical radial fluxes in the 1/nu regime

摘要:

在考虑相对论效应的情况下计算了1/nu区的径向新经典电子通量,并与非相对论方法的结果进行了比较。处理是基于相对论漂移动力学方程与相对论麦克斯韦-尤特纳分布函数给出的热力学平衡。结果表明,在T_e<100 keV的聚变温度范围内,相对论效应使径向通量减小不超过10%。这种相当小的影响是由两个抵消因素引起的相对论校正的非单调温度依赖性的结果:从散装的贡献减少和显着扩大与温度增长的能量范围的电子有助于运输。本文给出的径向通量的相对论公式是用一组相对论热力学力来表示的,这组力与正则力不同,因为它含有一个依赖于温度的相对论修正项。在同一时间,这个配方允许应用程序的非相对论求解器目前用于计算的单能输运系数。

英文摘要:

The radial neoclassical fluxes of electrons in the 1/nu regime are calculated with relativistic effects taken into account and compared with those in the non-relativistic approach. The treatment is based on the relativistic drift-kinetic equation with the thermodynamic equilibrium given by the relativistic Maxwell-Jüttner distribution function. It is found that for the range of fusion temperatures, T_e<100 keV, the relativistic effects produce a reduction of the radial fluxes which does not exceed 10%. This rather small effect is a consequence of the non-monotonic temperature dependence of the relativistic correction caused by two counteracting factors: a reduction of the contribution from the bulk and a significant broadening with the temperature growth of the energy range of electrons contributing to transport. The relativistic formulation for the radial fluxes given in this paper is expressed in terms of a set of relativistic thermodynamic forces which is not identical to the canonical set since it contains an additional relativistic correction term dependent on the temperature. At the same time, this formulation allows application of the non-relativistic solvers currently used for calculation of mono-energetic transport coefficients.
