A model of two-temperature plasma with strong large-scale turbulence: dynamic equations, thermodynamics and transport coefficients

Nicholas B Volkov1999年Plasma Physics and Controlled FusionIF 2.2出版社

A complete phenomenological model of the two-temperature plasma with developed (strong) turbulence is proposed and investigated. The model is suitable for the simulation of the physical processes occurring in the plasmas of fast classical (Z-) and screw (S-) pinches at the stagnation stage. The notion of the turbulent-thermal entropy is introduced for plasmas with strong turbulence and a dynamic equation describing the evolution of the plasma in space and time is derived. The equations of state proposed allow one to determine unambiguously the thermodynamic functions and transport coefficients for a plasma with strong large-scale turbulence. Peculiarities of the establishment of thermodynamic equilibrium in a two-temperature plasma with strong large-scale turbulence are discussed.

完全な現象論的モデルが、発達した(強い)乱流を伴う二温度プラズマに対して提案され、調査された。このモデルは、高速Z(軸方向)ピンチおよびS(螺旋)ピンチのプラズマにおいて、停滞段階で生じる物理過程のシミュレーションに適している。強い乱流を伴うプラズマに対して、乱流-熱エントロピーの概念が導入され、空間および時間におけるプラズマの進化を記述する動的方程式が導出された。提案された状態方程式により、強い大規模乱流を伴うプラズマの熱力学関数および輸送係数を一義的に決定することが可能となる。強い大規模乱流を伴う二温度プラズマにおける熱力学的平衡の確立の特異性について議論された。
