Abstract

The plasma thermal-chemical instability was studied in a direct current (DC) gas discharge with a detailed H2 O2 N2 kinetic scheme. A set of time-dependent zero-dimensional species and energy equations was formulated and then solved numerically. The results showed that plasma kinetic pathways and elementary H2 O2 N2 chemistry were coupled and hence modified the chemical modes of plasma instability. A better understanding of the dynamics and chemical modes involved in the plasma thermal-chemical instability may contribute to the future development of the non-equilibrium plasma applications for efficient ignition and material synthesis.
