This project employs pure electron plasmas to study two-dimensional nearly inviscid fluid flow. The project unites the efforts of researchers with experience in pure electron plasmas and plasma fluid experiments with those with experience in the analytic and numerical analysis of geophysical flows and two-dimensional turbulence. Key areas of study will include determining how complex fluid systems equilibrate and relax toward their late-time states, how they create structures and spatial patterns, and how the dynamics differ in flows that are strictly Hamiltonian from those with forcing and dissipation such that the phase space has both repelling and attracting regions. The results of this work will have broad impact on turbulence theory, pattern formation, planetary atmospheres, oceanography, and star and planet formation.

这个项目使用纯电子等离子体来研究二维几乎无粘的流体流动。该项目将在纯电子等离子体和等离子体流体实验方面有经验的研究人员与在地球物理流动和二维湍流的分析和数值分析方面有经验的研究人员联合起来。研究的关键领域将包括确定复杂的流体系统如何向其后期状态平衡和松弛，它们如何创建结构和空间模式，以及严格哈密顿的流动与具有强迫和耗散的流动中的动力学如何不同，从而使相空间既有排斥区又有吸引区。这项工作的结果将对湍流理论、模式形成、行星大气、海洋学以及恒星和行星的形成产生广泛的影响。
