Influence of Vortex Electron Currents on Transport Processes in 2-D Photoplasma of Sodium–Noble Gas Mixtures

Abstract

This study has been performed for a 2-D fluid model of sodium photoplasma with noble gas mixtures in two-chamber cells. A source of photoexcitation of sodium resonance levels is located in the first (source) chamber. In contrast, plasma in the second (diffusion) chamber is formed due to the transport of charges from the first chamber. The created photoplasma at different excitation rate, gas type, and pressure have been studied. Unlike previous investigations of photoplasma based on the study of the temporal and spatial distributions of plasma parameters, in this research, the transport processes also have been investigated explicitly. The different flux components throughout the cell and the corresponding variations of electron temperature gradient affect the fluxes magnitude and, consequently, the electromotive force (EMF). Generally speaking, the findings from the model contribute to that, for the optimization of photoplasma cells, the study of transport processes must be focused.
