强磁场中κ分布完全电离等离子体的输运系数

Transport coefficients of the fully ionized plasma with kappa-distribution and in strong magnetic field

Guo Ran, Du Jiulin

摘要:

研究了强磁场中具有κ分布的完全电离等离子体中的输运过程。通过分析电流密度和热通量,推导出了相应的输运系数,包括电导率、热导率和热电系数。此外,我们还导出了κ分布等离子体中的Hall、Nernst和Leduc-Righi效应系数。结果表明,这些新的输运系数强烈依赖于κ参数,只有在极限κ到无穷大,他们恢复传统的形式在等离子体的麦克斯韦分布的基础上。我们还数值分析了κ参数在依赖于κ的输运系数中的作用。

英文摘要:

Transport processes in the fully ionized plasma with kappa-distribution and in strong magnetic field are studied. By analyzing the current density and the heat flux in the kappa-distributed plasma, we derive the corresponding transport coefficients, including the electric conductivity, the thermal conductivity and thermoelectric coefficient. Besides, we derive the coefficients of Hall, Nernst and Leduc-Righi effects in the kappa-distributed plasma. It is shown that these new transport coefficients depend strongly on the kappa-parameter and only in the limit kappa to infinity, they recover the traditional forms in the plasma based on a Maxwellian distribution. We also numerically analyze the role of the kappa-parameter in the kappa-dependent transport coefficients.
