The Role Of Current-Free Double-Layers In Plasma Propulsion
Year:2008
Research Areas

Information
Abstract
Current free double layers are found in plasmas with two-temperature electron popu- lations. A model of the expansion of this type of plasma in a Laval nozzle is presented. Stationary double layers form for a limited range of plasma parameters. They can be lo- cated either on the divergent nozzle, or the throat, or the convergent nozzle; in the two last cases, a non-neutral spatial rippling remain downstream of them. Relative gains in plasma propulsion parameters are found for moderately low values of hot electron den- sity; gains tend to be larger when electrons are hotter and for larger nozzle expansion ratios. Both propulsion gains and double layer formation are associated to the anomalous thermodynamic properties of the plasma.
