Abstract : This report results from a contract tasking Institute for High Temperature - RAS (IVTAN) as follows: We plan to use high voltage capacity HF plasma generator to create longitudinal plasmoid in high-speed vortex gas flow and study of plasmoid physical properties in this Project. There is simple tuning of longitudinal plasmoid parameters by power feedback between capacity HF power supply and this plasmoid (tuning of resonance regime). There are optimal conditions for obtaining longitudinal plasma vortex by combined discharge plasma generator: high voltage pulse repetitive generator (ionizer) and continuous high current HF generator simultaneously. These conditions are absent in arc discharge of a traditional plasmatron. So, capacity HF plasma generator is optimal one for stable longitudinal plasmoid creation in high-speed vortex gas flow. Remember that we are succeeded in generation of a longitudinal HF plasmoid (up to 2 m) in high-speed vortex airflow at 0.8 and static pressure about Pst Bar namely. Stimulated vibration-translation V-T relaxation and electronic exited energy level-translation relaxation are possible in a longitudinal non-equilibrium plasmoid. The main goal of this Proposal is a study of plasma-chemical kinetics and stimulated relaxation processes in longitudinal non-equilibrium plasmoid and their roles in vortex structure and dynamics. This Proposal is devoted to study of physical properties of longitudinal plasmoid created by capacity HF discharge in high-speed vortex gas flow at different gas flow parameters and capacity HF discharge parameters.
