Charged-particle transport models for global models

Abstract This work analyses the influence of different charged-particle transport models on global modeling low-temperature plasmas. The simulations use LisbOn KInetics simulation tool, calculating loss frequency due to with various formulations, categorized into two large groups: ambipolar-based and h -factor models. are applied description (i) a DC discharge in oxygen (as example an electronegative multi-ion plasma), at low intermediate pressures, adopting validated kinetic scheme as reference model; (ii) microwave helium electropositive from atmospheric proposing validating updated that bridges previous models, adjusted separately for pressures pressure. analysis shows using can result uncertainties 20%–60% 8%–115% characteristics helium, respectively, larger dispersion pressure electron density. spreading results is observed also densities main plasma species, corresponding up 60 % within 50%–150% respectively. Since accounts more than $50\%$?> 50 total charge losses, this mechanism should always be part quantitative sensitivity scheme, considering several validity domains, according electro-positive/-negative single-/multi-ion under study low/high conditions considered.
