Thermophoresis in Plasma with Structures of Charged Dust Particles

摘要

The phenomenon of thermophoresis in a gas discharge in neon is studied in the presence of structures of charged dust particles. This system can simulate gas with combustion products in the form of a condensed dispersed phase. The relationship of the thermophoresis force acting on charged dust particles in a plasma with their concentration and gas pressure is analyzed. It is shown that with decreasing gas pressure the dependence of the thermophoresis force on the concentration of dust particles increases due to the mutual screening of the dust particles.
