Parallel flows and turbulence in a linear plasma machine

O F Castellanos, E Anabitarte, J M Sentíes, C. Hidalgo, M A Pedrosa2005年Plasma Physics and Controlled FusionIF 2.2出版社

Experimental evidence of parallel flows dynamically coupled to radial turbulent transport is reported in a linear plasma machine (SLPM). Probability density functions (PDFs) for parallel flows and transport are different. PDFs for transport show clear non-gaussian features with large and sporadic bursts and PDFs of parallel flows are rather gaussian. Plasma profiles of parallel Mach number (in the range 0.1–0.3) show gradients dM||/dr comparable to 1/Ln. Experimental results show that the dynamical coupling between transport and flows shows differences at different plasma radii. The degree of coupling also shows variations with plasma heating conditions. These findings suggest that, although turbulence can be considered as quasi-bidimensional in magnetized plasmas, parallel dynamics still play an important role in the regulation of radial transport.

平行流と径方向乱流輸送との動的結合の実験的証拠が、線形プラズマ装置(SLPM)において報告されている。平行流と輸送に関する確率密度関数(PDF)は異なる。輸送に関するPDFは、大きな間欠的バーストを伴う明確な非ガウス性を示す一方、平行流に関するPDFはほぼガウス分布である。平行マッハ数(0.1〜0.3の範囲)のプラズマ分布は、1/Lnに匹敵する勾配dM||/drを示す。実験結果は、輸送と流れの間の動的結合がプラズマ半径によって異なることを示している。結合の程度は、プラズマ加熱条件によっても変化する。これらの知見は、磁化プラズマにおける乱流が準二次元的とみなせるものの、平行ダイナミクスが径方向輸送の制御において依然として重要な役割を果たすことを示唆している。
