论文摘要
当湍流结构在衰减前更频繁地分裂时，中性流体剪切流中会形成持续的湍流。在此研究是否可以扩展到线性磁化等离子体，并将其与管道流动的行为进行比较。随着控制参数的增加，已知磁化等离子体中的动力学经历了从准碘到锁定相位到弱湍流状态的相位的几次变化。当相锁状态分解时，分裂时间接近减少的寿命，反映了自我维持的湍流，如管道流量所知。
When turbulent structures split more frequently before they decay, persistent turbulence forms in neutral fluid shear flows. Whether this concept can be extended to linear magnetized plasmas is investigated here and compared to the behavior of the pipe flow. With increasing control parameter the dynamics in the magnetized plasmas is known to undergo several changes from a quasiperiodic to a phase locked to a weakly turbulent regime. When the phase-locked regime breaks down, the splitting time approaches the decreasing lifetime reflecting self-sustained turbulence, as known from the pipe flow.
