Experimental study of drift wave turbulence and anomalous transport

B Fischer, M Kramer1989年Plasma Physics and Controlled FusionIF 2.2出版社

Strong drift wave turbulence and anomalous transport have been investigated under conditions of large ion dynamics effects, i.e. the major part of the fluctuation energy spectrum is located at perpendicular wavenumbers kperpendicular to approximately= rho s-1 ( rho s=(Te/mi omega ci2)1/2 being the effective ion gyroradius. It was found that the stationary turbulence and the particle transport are determined both by the linear kinetic theory of the drift waves and nonlinear effects. The kperpendicular to -scaling of the spectra in the range kperpendicular to rho s>1 obeys the numerical results obtained from the Hasegawa-Mima model. The phase difference between the density and the potential fluctuations agrees reasonably well with the predictions of the linear theory. The resulting fluctuation-induced particle flux fits to estimates of the diffusion coefficient evaluated from the density fluctuation spectra.

強いドリフト波乱流と異常輸送が、大きなイオン動力学効果の条件下で調査された。すなわち、ゆらぎエネルギー・スペクトルの主要部分は、垂直波数k⊥≒ρs⁻¹(ρs=(Te/miωci²)¹/²は有効イオンジャイロ半径)に位置する。定常乱流と粒子輸送は、ドリフト波の線形運動論と非線形効果の両方によって決定されることが見出された。k⊥ρs>1の範囲におけるスペクトルのk⊥スケーリングは、長谷川・三間モデルから得られた数値結果に従う。密度ゆらぎと電位ゆらぎの間の位相差は、線形理論の予測と合理的によく一致する。結果として生じるゆらぎ誘起粒子フラックスは、密度ゆらぎスペクトルから評価された拡散係数の推定値に適合する。
