In the current study, we conduct a parametric numerical investigation where 0D atmospheric pressure (high energy density) discharges simulations are coupled with 1D opposed flow diffusion flames simulations to study the influence of NPHFD on the extinction strain rate. In addition, the individual and combined contributions of the discharge kinetic and thermal effects are studied.
It is found that extinction strain rates are exponentially dependent on discharge energy density. Moreover, in high energy density discharges, extinction strain rates are dependent on the kinetic and thermal effects of the discharges in a synergetic manner.
