We acknowledge that a DBD can perform each within a filamentary and uniform regime [28,38]. Even so, it is actually most usually filamentary (i.e., consisting of microdischarges and their afterflows). Consequently, the modelling final results in Figure eight are shown for each the microdischarges and their afterglows of a filamentary plasma. For both situations, outcomes have been calculated for a plasma phase containing vibrationally excited N2 and plasma-generated radicals, too as a plasma phase containing only vibrationally excited N2 (denoted “vib. only” inside the legend of Figure eight).
