摘要:

尘埃等离子体是电子、离子以及处于中性气体背景中的亚微米至微米尺寸大质量带电固体颗粒的混合物。尘埃颗粒介质在不同的背景等离子体条件下表现出流体(液体)以及类固体特性。由于外部扰动和内部不稳定性,它支持各种线性和非线性动力学结构。尘埃等离子体介质中的涡旋或相干结构是一种自持动力学结构,由不稳定性或外部强迫形成。在这篇综述文章中,作者讨论了以往关于非磁化以及磁化尘埃等离子体中涡旋和相干结构的理论、实验和计算研究。文中详细讨论了在尘埃颗粒介质中形成涡旋的可能机制,并综述了关于涡旋演化及其与湍流相关性的研究。

英文摘要:

Dusty plasma is an admixture of electrons, ions, and massive charged solid particles of sub-micron to micron-sized in the background of neutral gas. The dust grain medium exhibits fluid (liquid) as well as solid-like characteristics at different background plasma conditions. It supports various linear and non-linear dynamical structures because of the external perturbation and internal instabilities. The vortical or coherent structure in the dusty plasma medium is a kind of self-sustained dynamical structure that is formed either by instabilities or external forcing. In this review article, the author discusses the past theoretical, experimental, and computational investigations on vortical and coherent structures in unmagnetized as well as in magnetized dusty plasma. The possible mechanisms to form vortices in dust grain medium are discussed in detail. The studies on the evolution of vortices and their correlation with turbulence are also reviewed.
