The plasma thermal-chemical instability was studied in the direct current (DC) and pulsed H2 O2 N2 gas discharges. A set of time-dependent one-dimensional equations was formulated and then solved numerically. The results showed that H2 O2 chemistry and pulse parameters (repetition frequency and pulse width) could change the balance between heat/species accumulation and convective loss and hence modify the growth of plasma instability. A better understanding of the pulse scheme and fuel chemistry involved in the plasma thermal-chemical instability may contribute to the future development of the plasma-assisted ultra-lean engine.
