电磁等离子体湍流在超精细(即,在先进的仿星器聚变实验温德尔斯坦7-AS [H. Renner,Plasma Phys. Controlled Fusion 31,1579(1989)],通过非线性陀螺动力学模拟。它表明,高振幅径向流光也可能存在于非托卡马克装置,提高电子热通量的实验相关值。此外,充分发展的湍流的一些统计特性进行了计算,突出的(共同)存在,性质和自生带状流场的作用。
Electromagnetic plasma turbulence at hyperfine (i.e., electron gyroradius) scales is studied in the geometry of an advanced stellarator fusion experiment, Wendelstein 7-AS [H. Renner, Plasma Phys. Controlled Fusion 31, 1579 (1989)], by means of nonlinear gyrokinetic simulations. It is demonstrated that high-amplitude radial streamers may also exist in non-tokamak devices, raising the electron heat flux to experimentally relevant values. Moreover, some statistical characteristics of the fully developed turbulence are computed, highlighting the (co-)existence, nature, and role of self-generated zonal flows and fields.
