内容記述 | A stimulated Raman scattering in a plasma represents a resonant three-wave interaction which involves the nonlinear coupling of an electromagnetic pump into a scattered electromagnetic wave plus an electron plasma wave. In this paper, we concentrate on a nonlinear evolution of stimulated Raman backscattering in an open convective weakly confined model. In recent fluid simulations, rich spatio-temporal complexity that exhibits a transition to intermittency and chaos was revealed. However, this model has failed to account for a realistic entropy balance due to an anomalous dissipation. We introduce a hybrid-three-wave interaction model to include a phenomenological kinetic dissipation due to particle trapping and plasma wave breaking. Furthermore, we propose an open plasma model with realistic current-free boundaries to compare with a closed-isolated case. Under a continual free energy supply we vary a transport parameter to study a kinetic self-organization. In simulations, macro and micro scale complexities develop, which saturate and get attracted to definite dynamical states, such as: quasi-steady, quasi-periodic and intermittent ones. At this point, an important consistency of above findings with a general scenario of a self-organization in plasmas can be claimed. | |||||
