摘要: Computational simulations of air glow discharge phenomena in the pressure range typical plasma actuator applications for high speed flow control are presented. The model is based on a self-consistent, multispecies, and multitemperature continuum description plasma. A reduced suitable multidimensional with 11 species 21 gas phase chemical reactions validated against experimental results literature. predicts experimentally observed mode operation, current-voltage characteristics discharge, spatial profiles electron temperature positive ion number densities. For pressures order 1 Torr, O2+ N2+ dominant concentration O− negative comparable to concentration. two-dimensional structure predicted by found be agreement qualitative observations from experiments.
