Turbulent viscosity bifurcation and the H-mode

G.M. Staebler, R.R. Dominguez1993年被引用 30Nuclear FusionIF 3出版社

The quasi-linear perpendicular viscous stress due to kinetic ion temperature gradient (ITG) modes in a sheared slab is shown to possess a maximum at a critical value for the gradient of the equilibrium electric field. This feature is present for a wide range of plasma parameters. As previously demonstrated, the ITG mode is stabilized for sufficiently large electric field gradients. It is shown how the existence of a maximum in the turbulent viscosity of ITG modes can play a role in a bifurcation theory of the H-mode. Such a model has the novel feature that the ITG mode is responsible for both the observed bifurcation in the electric field gradient and the imposed transport as it becomes stabilized

せん断スラブにおける運動論的イオン温度勾配(ITG)モードによる垂直粘性応力は、平衡電場勾配の臨界値において最大値を示すことが示されている。この特徴は、広範囲のプラズマパラメータにわたって存在する。先に実証されたように、ITGモードは十分に大きな電場勾配に対して安定化される。ITGモードの乱流粘性における最大値の存在が、Hモードの分岐理論においてどのように役割を果たし得るかが示される。このようなモデルは、電場勾配における観測された分岐と、ITGモードが安定化される際の課された輸送の両方が、ITGモードに起因するという新規な特徴を有する。
