摘要: A fluid model of the magnetic presheath in a weakly turbulent multicomponent plasma consisting electrons and several positive ion components is presented. Turbulent particle source terms continuity equations momentum balance for are derived from basic principles [Plasma Phys. Controlled Fusion 47, 685 (2005)], i.e., by means ensemble averaging procedure statistical theory turbulence. Then unknown correlations between fluctuating quantities occurring replaced with phenomenological expressions based on analogy classical transport. The remaining correlation equations, which responsible explicit coupling different components, reduce to corresponding when transport corrections negligible (i.e., “quiescent” plasmas). Under certain conditions regard...
