Effect of turbulence spreading on subcritical turbulence in inhomogeneous plasmas. (English) Zbl 1130.76343
Summary: The influence of the turbulence spreading is studied on the self-sustained turbulence which is induced by the subcritical instability. It is found that there is a minimum system size that can sustain the self-sustained turbulence, and an analytic formula is derived. The generalization of the Maxwell’s construction rule is also derived.
