磁场剪切对离子温度梯度模带状流产生的影响
Magnetic shear effect on zonal flow generation in ion-temperature-gradient mode turbulence
摘要
Abstract
By decoupling the nonlinear fluid equations of ion-temperature-gradient (ITG) mode,the zonal flow-drift wave nonlinear dynamical equation including magnetic shear is derived.The role of magnetic shear for zonal flow generation by ITG mode turbulence is studied using a four-wave interaction model of modulational instability.Finally we can draw the conclusion that within a smaller range of k∥,as |k∥|increases,the growth rate of zonal flow is also increased.关键词
