利用输运程序分析了螺旋等离子体中纬向流在输运势垒形成中的作用。一组一维输运方程进行了分析,包括纬向流的影响。当等离子体状态处于强正径向电场时,湍流输运系数被抑制。这种湍流输运的分叉是由纬向流阻尼率的变化引起的。从理论上证明了环形等离子体中纬向流的阻尼率在整体约束中起着重要的作用。
The role of zonal flows in the formation of transport barrier in helical plasmas is analysed using the transport code. A set of one-dimensional transport equations is analysed, including the effect of zonal flows. The turbulent transport coefficient is shown to be suppressed when the plasma state takes the strong positive radial electric field. This bifurcation of the turbulent transport is newly caused by the change of the damping rate of zonal flows. It is theoretically demonstrated that the damping rate of zonal flows plays an important role in global confinement in toroidal plasmas.
